Description

Technical Field

[0001] The invention relates to the technical field of filling devices, and in particular to a goat milk powder filling device and a filling method with a self-cleaning function. Background Art

[0002] Goat milk powder is milk powder made from goat milk as raw material, and has rich nutrients. When producing and processing goat milk powder, in order to facilitate transportation and storage, it is necessary to use a filling device to fill it. During the use of the existing filling device, in order to prevent the goat milk powder from caking and affecting the quality, a stirring device is added to stir the goat milk powder in the filler. Due to the addition of the stirring device, some goat milk powder will inevitably adhere to the stirring device after the filling is completed, and some goat milk powder will remain on the inner wall of the filling machine. If the residual goat milk powder is not cleaned up in time, it will not only cause waste but also cause pollution to subsequent products and affect product quality. At present, the cleaning of the residual goat milk powder in the filling machine is done manually, and not only the cleaning effect is not ideal, but also the possibility of secondary pollution due to improper operation. Therefore, it is necessary to design a goat milk powder filling device and filling method with self-cleaning function. Summary of the invention

[0017] A filling method of a goat milk powder filling device with a self-cleaning function, using the goat milk powder filling device with a self-cleaning function, comprises the following steps:

[0018] S1: Use brackets and other fixing parts to fix the device on the existing conveying equipment, open the opening and closing cover, put the goat milk powder to be filled into the filling machine, reset the opening and closing cover, and then start the conveying equipment and the motor at the same time;

[0019] S2: When there is enough goat milk powder in the filling machine, the motor works to drive the rotating rod to rotate through the driving shaft. At this time, the rotation resistance of the stirring blade is greater than the elastic potential energy of the torsion spring 1, so the stirring blade will rotate a certain angle on the rotating rod to drive the turntable to rotate at the same time. At this time, the screw rod 1 and the screw rod 2 rotate at the same time, driving the connecting frame and the moving block to move down a certain distance at the same time;

[0020] S3: The downward movement of the connecting frame causes the two scraping rods to swing toward the rotating rod and keep them separated from the inner wall of the filling machine through the cooperation of the swing rack on the pulling frame and the swing gear on the swing shaft. The downward movement of the moving block drives the fixing ring to move downward through the mounting frame, so that the multiple protrusions are separated from the top rod. At this time, the rotation of the rotating rod drives the stirring blade and the scraping rod to rotate in the filling machine at the same time, stirring the goat milk powder to prevent it from agglomerating. Since the scraping rod is separated from the inner wall of the filling machine, the rotation resistance of the rotating rod will not be increased, and the goat milk powder attached to the inner wall of the filling machine will not be heated and deteriorated due to long-term friction and extrusion.

[0021] S4: During the operation of the motor, the drive shaft drives the transmission shaft to rotate through the belt transmission structure, thereby causing the incomplete gear ring to rotate. When the tank body on the conveying device moves to the lower end of the filling port, the conveying device stops running, and the incomplete gear ring is in meshing state with the fixed gear. At this time, the driving screw rotates to cause the trigger rod to move downward. Through the design of multiple surfaces on the trigger rod, it drives the moving frame to move simultaneously during the downward movement process.

[0022] S5: The moving frame moves half the stroke quickly and remains stationary for a period of time. At this time, the opening and closing plate is driven to rotate 90° through the cooperation of the opening and closing rack and the opening and closing gear. The filling port is at the maximum opening and the empty can can be filled quickly. Then the moving frame moves half the stroke slowly, and the opening and closing plate continues to rotate 90° slowly until the filling port is closed again, so that the filling port opening is gradually reduced for slow filling to the specified weight. After the moving frame moves to the maximum stroke, the incomplete gear ring is separated from the fixed gear. At this time, the conveying equipment continues to run to send away the filled can body. At the same time, the elastic force of the second torsion spring causes the driving screw to reset and rotate, so that the trigger rod is reset, and the moving frame is also reset under the elastic force of the second tension spring. Since the opening and closing shaft and the opening and closing gear are connected by a one-way bearing, the opening and closing shaft does not rotate during the reset process, and the closing effect of the opening and closing plate on the filling port can be maintained;

[0023] S6: Repeat steps S2-S5 until the goat milk powder content in the filling machine is lower than the fillable amount, place a separate collecting tank on the conveying equipment and move it to the lower end of the filling port. At this time, due to the low content of goat milk powder, the elastic force of the torsion spring 1 is greater than the rotational resistance of the stirring blade. Therefore, the turntable rotates and resets in the rotating rod, driving the screw rod 1 and the screw rod 2 to reverse and reset, and the connecting frame and the moving block move up and reset, driving the scraper rod to open outward and fit the inner wall of the filling machine, and the fixed ring moves up so that the push rod contacts the upper surface of the fixed ring. At this time, when the driving shaft continues to rotate, multiple protrusions periodically contact the push rod, so that the rotating rod moves up and down during the rotation process, and the scraper rod scrapes off the residual goat milk powder attached to the inner wall of the filling machine. At the same time, due to the up and down movement of the rotating rod, part of the goat milk powder attached to the rotating rod, the stirring blade and the scraper rod will also be shaken off;

[0024] S7: When the goat milk powder content is insufficient, the connection relationship between the drive shaft and the transmission shaft remains unchanged. At this time, the opening and closing plate still maintains the same open state, and the goat milk powder remaining in the filling machine is put into the collection tank to clean the inner wall of the filling machine, so as to avoid the residual goat milk powder from contaminating the subsequent goat milk powder and affecting the product quality.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1: Through the cooperation of the anti-caking part and the scraping part, when the motor drives the rotating rod to rotate, the stirring process and the shaking-off cleaning process can be switched by utilizing the rotation resistance applied to the stirring blade by the different contents of goat milk powder in the filling machine. When the content of goat milk powder is sufficient, the stirring blade and the scraping rod are automatically stirred at the same time. After the filling of goat milk powder is completed, the scraping rod is attached to the inner wall of the filling machine and the rotating rod is rotated horizontally while shaking up and down to clean the residual goat milk powder. The cleaning effect is more ideal, avoiding the problem of contamination of subsequent products affecting the quality.

[0027] 2: Through the cooperation of the opening and closing gear, the opening and closing rack, the moving frame and the trigger rod, the rotation angle and rotation speed of the opening and closing plate in the filling port can be adjusted, so that the opening and closing conditions and the opening size of the filling port at different times can be controlled, and the filling speed can be adjusted according to the filling volume to achieve more accurate filling control.

[0028] 3: Through the cooperation of the transmission mechanism and the drive shaft, the opening and closing of the filling port can be controlled at the same time by using the motor, and the time proportion of the stirring process and the filling process in the same cycle can be more accurately controlled, ensuring that the goat milk powder being filled can be effectively stirred, thereby ensuring the quality of the goat milk powder product.

[0029] In summary, the present invention can automatically adjust the installation angle of the scraper rod and the contact relationship between the rotating rod and the driving shaft according to the change of the rotational resistance driven by the goat milk powder content in the filling machine, and can fully stir the goat milk powder when the goat milk powder content is sufficient to prevent agglomeration. After the filling is completed, the residual goat milk powder can be effectively cleaned up to ensure the product quality, and with the progress of the stirring or cleaning operation, the filling port will automatically match the corresponding switch state and opening size, so as to achieve more accurate filling processing.

DETAILED DESCRIPTION

[0048] Reference Figure 1 , a goat milk powder filling device with a self-cleaning function, comprising a filling port 2 fixedly installed at the bottom of the filling machine 1. When the filling machine 1 is used, it cooperates with the existing conveying equipment for conveying the can body. The conveying equipment can transport the can body, convey the empty can to the lower end of the filling port 2 for filling, and send the can body after filling to the next process. Since the conveying equipment is an existing product, its working principle and specific structure are not elaborated here. The filling machine 1 is sealed with an opening and closing cover 3. The opening and closing cover 3 is removed, and the goat milk powder to be filled can be put into the top of the filling machine 1. During the filling process, the opening and closing cover 3 is kept sealed on the filling machine 1, which can prevent the goat milk powder from overflowing and prevent external impurities such as ash from entering the filling machine 1.

[0049] Reference Figure 1-Figure 17 A goat milk powder filling device with a self-cleaning function also includes an anti-caking part, which is used to stir the goat milk powder to prevent it from agglomerating in the filling machine 1. The anti-caking part includes a motor 5 fixedly mounted on the filling machine 1 through a mounting seat 4. The mounting seat 4 consists of a hollow cylinder and a circular plate with a circular hole. The hollow cylinder is fixed to the upper end of the filling machine 1, and the circular plate is fixed to the upper end of the hollow cylinder. The motor 5 is fixed on the circular plate, and the output end of the motor 5 corresponds to the position of the circular hole. The output end of the motor 5 is fixedly connected to a drive shaft 6. The motor 5 can specifically adopt a motor that can only rotate in one direction, which is common in daily life and work.

[0050] A rotating rod 7 is installed at the bottom of the driving shaft 6 through two lifting assemblies, and a plurality of stirring blades 8 are installed at one end of the rotating rod 7 located in the filling machine 1 through a rotating assembly. The lifting assembly is composed of a lifting groove 27, a lifting rod 28 and a tension spring 29. The lifting groove 27 is opened at the bottom of the driving shaft 6, and the lifting rod 28 is slidably installed in the lifting groove 27. A tension spring 29 is installed between the lifting groove 27 and the lifting rod 28. The cooperation between the lifting rod 28 and the lifting groove 27 enables the rotating rod 7 to move up and down relative to the driving shaft 6, while ensuring the transmission effect of the driving shaft 6 on the rotating rod 7. The design of the tension spring 29 can provide a driving effect for the reset of the rotating rod 7 after the rotating rod 7 moves relative to the driving shaft 6. When the driving shaft 6 rotates, the stirring blade 8 can be driven by the rotating rod 7 to rotate in the filling machine 1 to stir the goat milk powder, so as to avoid the agglomeration of the goat milk powder affecting the filling effect.

[0051] The rotating assembly is composed of a rotating shaft 11, a rotating disk 12, a torsion spring 13, a rotating groove and a plurality of sliders 10. The rotating groove is provided in the rotating rod 7. The rotating shaft 11 is rotatably installed in the rotating groove. The rotating disk 12 is fixedly installed on the rotating shaft 11. The torsion spring 13 is installed between the bottom of the rotating disk 12 and the rotating groove. The plurality of sliders 10 are respectively fixedly installed between the rotating disk 12 and the plurality of stirring blades 8. An arc groove matching with the slider 10 is provided on the side wall of the rotating rod 7, and the arc groove is interconnected with the rotating groove. The rotating groove and the arc groove are not marked in the figure. Through the cooperation of the rotating shaft 11 and the rotating disk 12, the plurality of stirring blades can be 8 can rotate horizontally on the rotating rod 7. The design of the torsion spring 13 can keep the angle of the turntable 12 unchanged in the rotating groove when the tangential force on the stirring blade 8 is less than the elastic force of the torsion spring 13. When the stirring blade 8 is used to stir the goat milk powder, if the goat milk powder content is sufficient, the rotation resistance on the stirring blade 8 will cause the turntable 12 to overcome the elastic force of the torsion spring 13 and rotate in the rotating groove. When it rotates to the maximum angle (that is, when the slider 10 rotates to the maximum position in the arc groove), it remains stationary. At this time, the rotation of the rotating rod 7 can drive the stirring blade 8 to stir the goat milk powder.

[0052] A pushing mechanism that cooperates with the mounting seat 4 is installed on the rotating assembly. The pushing mechanism is used to push the rotating rod 7 up and down to shake off the goat milk powder on it. The pushing mechanism is composed of a screw rod 21, a moving block 22, a mounting frame 23, a fixing ring 24, a push rod 26 and a plurality of protrusions 25. The screw rod 21 is fixedly installed on the top of the rotating shaft 11, and the moving block 22 is threadedly connected to the screw rod 21, and the moving block 22 slides up and down with the rotating rod 7. A moving groove that slides up and down with the moving block 22 is provided in the rotating rod 7. The moving groove is not marked in the figure. When the stirring blade 8 rotates relative to the rotating rod 7 due to the rotation resistance of the goat milk powder, the turntable 12 drives the screw rod 21 to rotate at the same time. At this time, the moving block 22 moves down in the moving groove, and the mounting frame 23 is fixedly installed on the top of the moving block 22. The mounting frame 23 is composed of a cross bar and two vertical bars, and the two vertical bars slide up and down. It is arranged on the rotating rod 7, the cross bar is fixed between the ends of the two vertical rods located outside the rotating rod 7, and the two vertical rods and the two lifting rods 28 are staggered and will not hinder each other. The fixing ring 24 is fixedly installed on the cross bar, and a plurality of protrusions 25 are fixedly installed on the fixing ring 24. The top rod 26 is fixedly installed in the mounting seat 4, and the top rod 26 cooperates with a plurality of protrusions 25. The height of the protrusion 25 is less than the length of the screw rod 21. The advantage of the size design here is that when the screw rod 21 rotates to drive the moving block 22 to rotate, the up and down movement distance of the fixing ring 24 can be greater than the height of the protrusion 25. Therefore, when the screw rod 21 rotates to drive the fixing ring 24 to move downward, the plurality of protrusions 25 can be separated from the top rod 26. At this time, the distance between the driving shaft 6 and the rotating rod 7 remains stationary, so that the stirring blade 8 outside the rotating rod 7 can exert a stable stirring effect on the goat milk powder;

[0053] When the content of goat milk powder in the filling machine 1 is less, the rotational resistance of the stirring blade 8 is less than the elastic potential energy of the torsion spring 13, so the turntable 12 will reversely reset and rotate relative to the rotating rod 7. At this time, the screw rod 21 rotates in the opposite direction to make the fixing ring 24 move up, so that the multiple protrusions 25 and the push rod 26 contact each other. At this time, as the driving shaft 6 drives the rotating rod 7 to rotate, the multiple protrusions 25 on the fixing ring 24 contact the push rod 26 in turn, and the push effect of the push rod 26 on the protrusions 25 is used to make the rotating rod 7 move downward relative to the driving shaft 6, and when the positions of the protrusions 25 and the push rod 26 are staggered, the elastic force of the tension spring 29 is used to make the rotating rod 7 move up and reset. Therefore, the rotating rod 7 can be moved up and down during the rotation process, and the residual goat milk powder attached to the stirring blade 8 can be shaken off by its up and down movement to avoid residual goat milk powder.

[0054] The scraping part is used to remove the goat milk powder on the inner wall of the filling machine 1. The scraping part includes two scraping rods 9 swingably mounted on the rotating rod 7. The side walls of the two scraping rods 9 are fixedly mounted with connecting blocks 14, and the two connecting blocks 14 are fixedly mounted with swing blocks 15. Two swing grooves are provided on the side wall of the rotating rod 7, and swing shafts 16 are rotatably mounted in the two swing grooves. The two swing shafts 16 are respectively fixedly connected to the two swing blocks 15. Under the cooperation of the swing blocks 15 and the swing shafts 16, the scraping rods 9 can swing in the vertical direction relative to the rotating rod 7. When the scraping rods 9 swing Afterwards, the fitting state between the scraper rod 9 and the inner wall of the filling machine 1 can be regulated. Since the goat milk powder content in the filling machine 1 is sufficient during the filling process, in order to reduce the rotation resistance of the rotating rod 7 and avoid the goat milk powder at the inner wall of the filling machine 1 from being deteriorated due to continuous extrusion and friction, the scraper rod 9 needs to be separated from the inner wall of the filling machine 1. After the filling is completed, the scraper rod 9 is made to contact the inside of the filling machine 1. At this time, the scraper rod 9 is driven by the rotating rod 7 to rotate horizontally, and the goat milk powder attached to the inner wall of the filling machine 1 can be scraped off, so as to avoid the presence of goat milk powder residue on the inner wall of the filling machine 1 and ensure the cleaning effect of the goat milk powder.

[0055] An angle adjustment mechanism matched with the two scraping rods 9 is installed on the rotating assembly. The angle adjustment mechanism is used to adjust the installation angle of the two scraping rods 9 on the rotating rod 7. The angle adjustment mechanism is composed of a screw rod 18, a connecting frame 19, a pulling frame 20 and two swing gears 17. The screw rod 18 is fixedly installed at the bottom of the rotating shaft 11. The connecting frame 19 is threadedly connected to the screw rod 18, and the connecting frame 19 and the rotating rod 7 slide up and down. The two swing gears 17 are respectively fixedly installed on the two swing shafts 16, and the pulling frame 20 is fixedly installed at the bottom of the connecting frame 19. Two swing racks meshing with the corresponding swing gears 17 are fixedly installed on the pulling frame 20. The swing racks are not marked in the figure. When the stirring When the blade 8 is deflected at an angle relative to the rotating rod 7 by the rotational resistance of the goat milk powder, the rotation of the turntable 12 drives the screw rod 18 to rotate at the same time. At this time, the connecting frame 19 moves down in the rotating rod 7, so that the two swing racks on the pulling frame 20 move down at the same time, and the two scraping rods 9 are simultaneously moved toward the rotating rod 7 by utilizing the meshing effect of the swing rack and the swing gear 17 to achieve separation from the inner wall of the filler 1; and when the goat milk powder content is less and the turntable 12 is reset and rotated, the rotation of the screw rod 18 at this time causes the connecting frame 19 to move up, which will cause the two scraping rods 9 to open outward at the same time and fit the inner wall of the filler 1. Therefore, after the filling is completed, the rotation of the rotating rod 7 can be used to automatically scrape and sweep away the goat milk powder remaining on the inner wall of the filler 1.

[0056] The segmented filling part is used for segmented filling of goat milk powder. The segmented filling part includes an opening and closing plate 31 rotatably installed in the filling port 2 through an opening and closing shaft 30. When the opening and closing plate 31 rotates in the filling port 2, the switch of the filling port 2 can be controlled. By controlling the rotation angle of the opening and closing plate 31 in the filling port 2, the opening size of the filling port 2 can be adjusted, thereby realizing filling processing at different speeds. During specific operation, in the initial stage of filling, filling can be carried out at the fastest speed. When filling to a certain amount, slow filling can be used to more accurately control the filling weight and reduce filling errors.

[0057] The filling machine 1 is provided with a segmented drive assembly matched with the opening and closing shaft 30, and the segmented drive assembly is used to perform segmented control on the opening and closing angle of the opening and closing plate 31. The segmented drive assembly includes a moving frame 35 slidably mounted on the filling port 2. Both ends of the opening and closing shaft 30 outside the filling port 2 are equipped with opening and closing gears 33 through one-way bearings 32. Two opening and closing racks 36 matched with the corresponding opening and closing gears 33 are fixedly mounted on the moving frame 35. There are two support seats 34, and guide blocks 40 are fixedly installed in the two support seats 34. The two guide blocks 40 are fixedly connected to the moving frame 35, and tension springs 41 are installed between the two guide blocks 40 and the two support seats 34. Under the cooperation of the guide blocks 40 and the tension springs 41, when the moving frame 35 is not subjected to lateral force, its position on the filling port 2 can be kept unchanged. At this time, the opening and closing plate 31 is in a horizontal state in the filling port 2, which can ensure that the filling port 2 is in a sealed state. Fig. 9 As shown, when the movable frame 35 is moved to the right by the lateral pulling force, the opening and closing rack 36 thereon drives the opening and closing gear 33 to rotate. At this time, the one-way bearing 32 is in a locked state, and the opening and closing shaft 30 rotates simultaneously with the opening and closing gear 33, so that the opening and closing plate 31 rotates clockwise to open the filling port 2. When the movable frame 35 moves to the left, the one-way bearing 32 is in a rotating state, and the rotation of the opening and closing gear 33 cannot drive the opening and closing shaft 30 to rotate. At this time, the angle of the opening and closing plate 31 in the filling port 2 remains unchanged. By designing the dimensions of the opening and closing gear 33 and the opening and closing rack 36, the opening and closing gear 33 rotates 180° when the opening and closing rack 36 moves the maximum distance horizontally. In the process of the movable frame 35 moving to the right to the maximum distance, the filling port 2 can be changed from closed to open and then closed, and the filling port 2 can be kept in a closed state when the movable frame 35 moves to the left to reset.

[0058] The filling machine 1 is provided with a transmission mechanism matched with the driving shaft 6 and the moving frame 35, and the transmission mechanism is composed of a fixed plate 37, a driving screw 38, a trigger rod 39, a fixed plate 42, a second torsion spring 43, a transmission shaft 44, a belt transmission structure 45, an incomplete gear ring 46 and a fixed gear 47. The fixed plate 37 is fixedly mounted on the side wall of the filling machine 1, the driving screw 38 is rotatably mounted on the fixed plate 37, the trigger rod 39 is threadedly connected to the driving screw 38, a through groove matched with the trigger rod 39 is opened on the moving frame 35, the fixed plate 42 is fixedly mounted on the driving screw 38, the second torsion spring 43 is mounted between the fixed plate 42 and the fixed plate 37, the transmission shaft 44 is rotatably mounted on the top of the filling machine 1, the belt transmission structure 45 is mounted between the driving shaft 6 and the transmission shaft 44, and the incomplete gear ring 46 is mounted on the fixed plate 37. 6 is fixedly mounted on the transmission shaft 44, and the fixed gear 47 is fixedly mounted on the top of the driving screw rod 38, and the fixed gear 47 cooperates with the incomplete gear ring 46. Under the action of the belt transmission structure 45, when the motor 5 works to drive the driving shaft 6 to rotate, it can drive the transmission shaft 44 to rotate at the same time, and then under the meshing action of the incomplete gear ring 46 and the fixed gear 47, the transmission shaft 44 will be meshed with the fixed gear 47 for a certain period of time during the process of rotating one circle. At this time, the rotation of the transmission shaft 44 drives the driving screw rod 38 to rotate. When the driving screw rod 38 rotates, the torsion spring 43 rotates and deforms at the same time, and the trigger rod 39 moves down along the driving screw rod 38 at this time. The cooperation between the trigger rod 39 and the through groove on the moving frame 35 makes the moving frame 35 move to the right, thereby automatically controlling the switch of the filling port 2;

[0059] The belt drive structure 45 consists of a pulley 1, a pulley 2 and a belt, wherein the pulley 1 is fixedly mounted on the drive shaft 6, the pulley 2 is fixedly mounted on the transmission shaft 44, and the belt is mounted between the pulley 1 and the pulley 2. By designing the relative sizes of the pulley 1 and the pulley 2, the transmission ratio of the drive shaft 6 and the transmission shaft 44 can be controlled, wherein the drive shaft 6 is used to control the rotation of the stirring blade 8 and the scraper rod 9, and the transmission shaft 44 is used to control the switch of the filling port 2. By utilizing the design of the transmission ratio of the two, the device can be used to stir the goat milk powder and control the filling time within a certain period, thereby achieving the desired stirring effect and filling efficiency.

[0060] An initial surface 391, a push surface 1 392, an intermediate surface 393, a push surface 2 394 and an end surface 395 are sequentially arranged on the side wall of the end of the trigger rod 39 away from the filling port 2 from bottom to top. The initial surface 391, the intermediate surface 393 and the push surface 2 394 are all vertical planes, the push surface 1 392 and the push surface 2 394 are all inclined surfaces, and the lateral spacing between the intermediate surface 393 and the initial surface 391 is equal to the lateral spacing between the intermediate surface 393 and the end surface 395, and the lateral spacing between the initial surface 391 and the end surface 395 is equal to the length of the opening and closing rack 36. The push surface 1 The included angle between the first push surface 392 and the initial surface 391 is smaller than the included angle between the middle surface 393 and the second push surface 394. By designing the first push surface 392 and the second push surface 394, when the trigger rod 39 moves downward, the two push surfaces can be used to squeeze the through groove to make the movable frame 35 move to the right. Both of them push the movable frame 35 to move half of the maximum distance. Since the inclinations of the first push surface 392 and the second push surface 394 are different, the squeezing effects of the two on the through groove make the moving speed of the movable frame 35 different, so that the rotation speed of the opening and closing plate 31 can be controlled. Fig.17 When the pushing surface 1 392 squeezes the through groove, the opening and closing plate 31 will quickly rotate 90°. At this time, the filling port 2 is at its maximum opening. The squeezing of the through groove by the pushing surface 2 394 will cause the opening and closing plate 31 to continue to slowly rotate 90°, so that the filling port 2 is gradually closed from the maximum opening, thereby achieving rapid filling first and then gradual slow filling during the filling process.

[0061] In the present invention, a filling method of a goat milk powder filling device with a self-cleaning function comprises the following steps:

[0062] S1: Use a bracket or other fixing parts to fix the device on the existing conveying equipment, open the opening and closing cover 3, put the goat milk powder to be filled into the filling machine 1, reset the opening and closing cover 3, and then start the conveying equipment and the motor 5 at the same time;

[0063] S2: When there is enough goat milk powder in the filling machine 1, the motor 5 works to drive the rotating rod 7 to rotate through the driving shaft 6. At this time, the rotation resistance of the stirring blade 8 is greater than the elastic potential energy of the torsion spring 13, so the stirring blade 8 will rotate a certain angle on the rotating rod 7 to drive the turntable 12 to rotate at the same time. At this time, the screw rod 18 and the screw rod 21 rotate at the same time, driving the connecting frame 19 and the moving block 22 to move down a certain distance at the same time;

[0064] S3: The downward movement of the connecting frame 19 causes the two scraping rods 9 to swing toward the rotating rod 7 to maintain a separation state from the inner wall of the filling machine 1 through the cooperation of the swing rack on the pulling frame 20 and the swing gear 17 on the swing shaft 16. The downward movement of the moving block 22 drives the fixing ring 24 to move downward through the mounting frame 23, so that the multiple protrusions 25 are separated from the top rod 26. At this time, the rotation of the rotating rod 7 drives the stirring blade 8 and the scraping rod 9 to rotate in the filling machine 1 at the same time, stirring the goat milk powder to prevent it from agglomerating. Since the scraping rod 9 is separated from the inner wall of the filling machine 1, the rotation resistance of the rotating rod 7 will not be increased, and the goat milk powder attached to the inner wall of the filling machine 1 will not be heated and deteriorated due to long-term friction and extrusion;

[0065] S4: During the operation of the motor 5, the drive shaft 6 drives the drive shaft 44 to rotate through the belt drive structure 45, thereby causing the incomplete gear ring 46 to rotate. When the tank body on the conveying device moves to the lower end of the filling port 2, the conveying device stops running, and the incomplete gear ring 46 is in a meshing state with the fixed gear 47. At this time, the driving screw 38 rotates to cause the trigger rod 39 to move downward. Through the design of multiple surfaces on the trigger rod 39, it drives the moving frame 35 to move simultaneously during the downward movement process.

[0066] S5: The moving mode of the moving frame 35 is to first quickly move half of the stroke and keep still for a period of time. At this time, the opening and closing plate 31 is driven to rotate 90° through the cooperation of the opening and closing rack 36 and the opening and closing gear 33. The filling port 2 is at the maximum opening and the empty can can be quickly filled. Then the moving frame 35 slowly moves half of the stroke, and the opening and closing plate 31 is slowly rotated 90° until the filling port 2 is closed again, so that the opening of the filling port 2 is gradually reduced for slow filling to the specified weight. After the moving frame 35 moves to the maximum stroke, the incomplete gear ring 46 is separated from the fixed gear 47. At this time, the conveying equipment continues to run to send away the filled can body. At the same time, the elastic force of the torsion spring 2 43 causes the driving screw 38 to reset and rotate, so that the trigger rod 39 is reset, and the moving frame 35 is also reset under the elastic force of the tension spring 2 41. Since the opening and closing shaft 30 and the opening and closing gear 33 are connected by a one-way bearing 32, the opening and closing shaft 30 does not rotate during the reset process, and the closing effect of the opening and closing plate 31 on the filling port 2 can be maintained.

[0067] S6: Repeat steps S2-S5 until the goat milk powder content in the filling machine 1 is lower than the fillable amount, place a separate collecting tank on the conveying equipment and move it to the lower end of the filling port 2. At this time, due to the low content of goat milk powder, the elastic force of the torsion spring 13 is greater than the rotation resistance of the stirring blade 8. Therefore, the turntable 12 rotates and resets in the rotating rod 7 to drive the screw rod 18 and the screw rod 21 to reverse and reset, and the connecting frame 19 and the moving block 22 move up and reset, driving the scraper rod 9 to open outward and fit the inner wall of the filling machine 1, and the fixing ring 24 moves up so that the push rod 26 contacts the upper surface of the fixing ring 24. At this time, when the driving shaft 6 continues to rotate, the multiple protrusions 25 periodically contact the push rod 26, so that the rotating rod 7 moves up and down during the rotation process, and the scraper rod 9 scrapes off the residual goat milk powder attached to the inner wall of the filling machine 1. At the same time, due to the up and down movement of the rotating rod 7, part of the goat milk powder attached to the rotating rod 7, the stirring blade 8 and the scraper rod 9 will also be shaken off;

[0068] S7: When the goat milk powder content is insufficient, the connection relationship between the drive shaft 6 and the transmission shaft 44 remains unchanged. At this time, the opening and closing plate 31 still maintains the same open state, and the goat milk powder remaining in the filling machine 1 is put into the collecting tank to clean the inner wall of the filling machine 1, thereby preventing the residual goat milk powder from contaminating the subsequent goat milk powder and affecting the product quality.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.

5. A filling method of a goat milk powder filling device with a self-cleaning function, using the goat milk powder filling device with a self-cleaning function as claimed in claim 4, characterized in that: The following steps are involved: S1: using a bracket or other fixing parts to fix the device to the existing conveying equipment, opening the opening and closing cover (3), putting the goat milk powder to be filled into the filling machine (1), resetting the opening and closing cover (3), and then starting the conveying equipment and the motor (5) at the same time; S2: When the amount of goat milk powder in the filling machine (1) is sufficient, the motor (5) works to drive the rotating rod (7) to rotate through the driving shaft (6). At this time, the rotational resistance of the stirring blade (8) is greater than the elastic potential energy of the torsion spring 1 (13). Therefore, the stirring blade (8) will rotate on the rotating rod (7) at a certain angle to drive the turntable (12) to rotate at the same time. At this time, the screw rod 1 (18) and the screw rod 2 (21) rotate at the same time, driving the connecting frame (19) and the moving block (22) to move downward a certain distance at the same time; S3: The downward movement of the connecting frame (19) causes the two scraping rods (9) to swing toward the rotating rod (7) and maintain a separation state from the inner wall of the filling machine (1) through the cooperation of the swing rack on the pulling frame (20) and the swing gear (17) on the swing shaft (16). The downward movement of the moving block (22) drives the fixing ring (24) to move downward through the mounting frame (23), so that the plurality of protrusions (25) are separated from the top rod (26). At this time, the rotating rod (7) rotates to drive the stirring blade (8) and the scraping rod (9) to rotate in the filling machine (1) at the same time, stirring the goat milk powder to prevent it from agglomerating. Since the scraping rod (9) is separated from the inner wall of the filling machine (1), the rotation resistance of the rotating rod (7) will not be increased, and the goat milk powder attached to the inner wall of the filling machine (1) will not be heated and deteriorated due to long-term friction and extrusion; S4: During the operation of the motor (5), the drive shaft (6) drives the drive shaft (44) to rotate through the belt drive structure (45), thereby causing the incomplete gear ring (46) to rotate. When the tank body on the conveying device moves to the lower end of the filling port (2), the conveying device stops running, and the incomplete gear ring (46) and the fixed gear (47) are in a meshing state. At this time, the driving screw (38) rotates to cause the trigger rod (39) to move downward. Through the design of multiple surfaces on the trigger rod (39), the movable frame (35) is driven to move simultaneously during the downward movement process. S5: The moving frame (35) moves half the stroke quickly and remains stationary for a period of time. At this time, the opening and closing rack (36) and the opening and closing gear (33) drive the opening and closing plate (31) to rotate 90 degrees, and the filling port (2) is at the maximum opening to quickly fill the empty can. Then, the moving frame (35) moves half the stroke slowly, and the opening and closing plate (31) is slowly rotated 90 degrees until the filling port (2) is closed again, so that the opening of the filling port (2) is gradually reduced to slowly fill to the specified weight. After the moving frame (35) moves to the maximum stroke, , the incomplete gear ring (46) is separated from the fixed gear (47), and the conveying equipment continues to operate to transport the filled cans. At the same time, the elastic force of the second torsion spring (43) causes the driving screw (38) to reset and rotate, so that the trigger rod (39) is reset, and the movable frame (35) is also reset under the elastic force of the second tension spring (41). Since the opening and closing shaft (30) and the opening and closing gear (33) are connected by a one-way bearing (32), the opening and closing shaft (30) does not rotate during the reset process, and the opening and closing plate (31) can maintain the closing effect on the filling port (2); S6: Repeat steps S2-S5 until the goat milk powder content in the filling machine (1) is lower than the fillable amount, and place a separate collecting tank on the conveying device and move it to the lower end of the filling port (2). At this time, due to the low content of goat milk powder, the elastic force of the torsion spring 1 (13) is greater than the rotational resistance of the stirring blade (8), so the turntable (12) rotates and resets in the rotating rod (7), driving the screw rod 1 (18) and the screw rod 2 (21) to reverse and reset, and the connecting frame (19) and the moving block (22) move upward and reset, driving the scraper rod (9) to open outward. The rotating rod (7) is fitted with the inner wall of the filling machine (1), and the fixing ring (24) is moved upward so that the push rod (26) contacts the upper surface of the fixing ring (24). At this time, when the driving shaft (6) continues to rotate, the plurality of protrusions (25) periodically contact the push rod (26), so that the rotating rod (7) moves up and down during the rotation process, and the scraping rod (9) scrapes off the residual goat milk powder attached to the inner wall of the filling machine (1). At the same time, due to the up and down movement of the rotating rod (7), part of the goat milk powder attached to the rotating rod (7), the stirring blade (8) and the scraping rod (9) is also shaken off; S7: When the goat milk powder content is insufficient, the connection relationship between the drive shaft (6) and the transmission shaft (44) remains unchanged, and the opening and closing plate (31) remains in the same open state. The goat milk powder remaining in the filling machine (1) is put into the collection tank, so as to clean the inner wall of the filling machine (1) and prevent the residual goat milk powder from contaminating the subsequent goat milk powder and affecting the product quality.
