Description

Technical Field

[0001] This invention relates to the field of metering device technology, and in particular to a high-precision quantitative filling control device for a filling machine. Background Technology

[0002] A filling machine is a type of packaging equipment, and one of the most commonly used packaging machines. It is widely used in many industries such as food, beverage, chemical, pharmaceutical, and daily chemical. Common packaging machines include liquid filling machines, paste filling machines, and granule filling machines.

[0003] In the filling process, quantitative filling is one of the important functions of filling machines. For example, Chinese patent CN115402548B discloses a manual paste quantitative filling machine that uses a spiral blade to continuously feed paste into a sliding sleeve until the gas in the paste is squeezed out, thereby achieving a quantitative effect on the paste. In addition, the rotation of the baffle drives the slide tube and the rotating plate to rotate, so that the discharge port on the rotating plate and the discharge port on the fixed plate are closed, preventing the paste in the box from continuing to flow into the sliding sleeve and affecting the quantitative effect. Existing filling equipment can achieve quantitative filling of paste materials by using gas compression. However, in actual operation, paste materials not only have a certain degree of fluidity but also maintain a certain degree of viscosity. During the filling process, some paste materials will adhere to the inner wall of the discharge pipe and drip randomly under the action of gravity. The falling of materials will not only affect the quantitative filling accuracy, but also cause additional waste when the materials drip onto the surface of the filling machine.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This solution uses a material equalization component. Under the influence of gravity, the sealing plate rotates around the shaft, evenly distributing the material to the outside of the filling tube. When two sets of sealing plates come into contact with the inner wall of the filling tube, the sealing plates can seal the lower side of the filling tube, thus preventing the paste material from continuing to drip. This not only helps reduce the risk of large filling errors caused by continuous dripping of material, thereby improving the filling accuracy of the paste material, but also avoids additional material loss caused by the paste material dripping onto the main unit. 2. This solution, by setting up a sealing component and a counterweight, continuously seals the inside of the filling tube through the sealing plate. During the filling gap of the filling equipment, it effectively reduces the dripping of paste materials, thereby reducing additional material waste. The liquid collects in the bottom sealing plate, ensuring that the center of gravity of the overall sealing plate structure is always at the bottom, thus improving the sealing effect of the sealing plate on the inside of the filling tube and further reducing the risk of leakage of paste materials inside the filling tube. The push plate can limit the sealing plate, thereby preventing the sealing plate from moving further and ensuring the sealing effect of the sealing plate on the filling tube. While improving the material filling accuracy, it can also effectively improve the sensitivity and flexibility of the sealing component. 3. This solution uses a quantitative component to achieve quantitative material delivery through the deformation of the elastic sleeve. This not only effectively improves the filling accuracy but also keeps the amount of material inside the filling tube within an appropriate range. This reduces the risk of excessive filling pressure due to excessive material in the filling tube and thus minimizes the impact of filling pressure fluctuations on filling accuracy.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 8 The present invention provides a technical solution: A high-precision filling machine quantitative filling control device includes a frame 11 and a guide tube 19. A material storage tube 24 is fixedly connected to the lower outer surface of the guide tube 19, and a filling tube 37 is fixedly connected to the lower end of the material storage tube 24. A material leveling component for uniform filling is provided inside the filling tube 37. The material leveling component is used to intermittently seal the filling tube 37. The material leveling component includes a rotating shaft 43 that is rotatably connected to the inner surface of the filling tube 37. A sealing plate 44 is fixedly connected to the outer surface of the rotating shaft 43. The number of sealing plates 44 is four sets and they are arranged in a ring array. A sealing component is provided outside the material leveling component. The sealing component is used to lock and fix the sealing plate 44.

[0021] By adopting the above technical solution, when the filling machine quantitatively fills paste materials, the paste material is evenly fed into the guide tube 19. The storage tube 24 stores the material quantitatively according to its weight. After being temporarily stored in the storage tube 24, the paste material is injected into the filling tube 37. Then, under the action of gravity, the paste material flows downward along the inside of the filling tube 37. The rotating shaft 43 provides rotational support for the sealing plate 44, allowing the sealing plate 44 to rotate around the rotating shaft 43 as a fulcrum. When the material falls onto the upper side of the sealing plate 44... Under the influence of gravity, the sealing plate 44 rotates around the rotating shaft 43, thereby evenly distributing the material to the outside of the filling tube 37. When the sides of two sets of sealing plates 44 come into contact with the inner wall of the filling tube 37, the sealing plate 44 can seal the lower side of the filling tube 37, thereby preventing the paste material from continuing to drip. This not only helps to reduce the risk of large filling errors caused by continuous dripping of material, but also improves the filling accuracy of the paste material. At the same time, it can also prevent the paste material from dripping onto the main unit, causing additional material loss.

[0022] Specifically, such as Figure 6 As shown, a counterweight is provided on the inner side of the sealing plate 44. The counterweight includes a liquid storage cavity 45 embedded in the inner side of the sealing plate 44. The inner surface of the liquid storage cavity 45 is triangular. The liquid storage cavity 45 is filled with an appropriate amount of liquid. The four sets of liquid storage cavities 45 are connected to each other.

[0023] By adopting the above technical solution, in the non-filling state, a counterweight assembly is set up to ensure that the sealing plate 44 can continuously seal the inside of the pipe. The liquid storage chamber 45 inside the sealing plate 44 is used to store an appropriate amount of liquid. The liquid storage chambers 45 are connected to each other. Under its own gravity, the liquid will flow into the bottommost liquid storage chamber 45, thereby causing the center of gravity of the four sealing plates 44 to shift downward. This allows two of the sealing plates 44 to remain vertical, while the other two sealing plates 44 will be horizontal and in contact with the inner wall of the filling pipe 37. The sealing plate 44 can continuously seal the inside of the pipe. The filling tube 37 is sealed inside, which effectively reduces the dripping of paste material during the filling gap of the filling equipment, thereby reducing additional material waste. The inner wall of the liquid storage chamber 45 is inclined, which can effectively accelerate the flow of liquid inside the liquid storage chamber 45. During the rotation of the sealing plate 44, the liquid can be quickly collected into the bottom sealing plate 44, so that the center of gravity of the overall structure of the sealing plate 44 is always kept at the bottom. This improves the sealing effect of the sealing plate 44 on the inside of the filling tube 37, and further reduces the risk of leakage of paste material inside the filling tube 37.

[0024] Specifically, such as Figure 6 and Figure 8 As shown, the sealing assembly includes a receiving groove 46 embedded inside the filling tube 37. A rotating shaft 49 is fixedly connected to the inner surface of the receiving groove 46. A push plate 50 is rotatably connected to the outer surface of the rotating shaft 49. An expansion plate 47 is fixedly connected between the rotating shaft 49 and the receiving groove 46. A magnetic block 48 is fixedly connected to the inner surface of the expansion plate 47. The outer surface of the push plate 50, away from the expansion plate 47, slides in contact with the sealing plate 44.

[0025] By adopting the above technical solution, a drive frame 12 is rotatably connected to the upper outer surface of the frame 11. A metering platform 13 for placing the soft cylinder 14 is provided on the upper outer surface of the drive frame 12. During the rotation of the drive frame 12, the soft cylinder 14 is moved one by one to the lower side of the filling position through the metering platform 13, thereby realizing the continuous penetration of materials. The filling tube 37 is supported by the receiving groove 46 for the expansion plate 47. The expansion tube is made of elastic material and applies a certain elastic force to the push plate 50. During the filling process, the metering platform 13 is used to measure the elastic force of the soft cylinder 14. The measuring platform 13 continuously monitors the weight of the flexible cylinder 14. When the weight of the flexible cylinder 14 detected by the measuring platform 13 does not reach the preset value, the paste material will be continuously injected into the interior of the flexible cylinder 14. At this time, the two sets of magnetic blocks 48 on the surface of the expansion plate 47 become conductive. There are two sets of magnetic blocks 48, which are symmetrically distributed on both sides of the expansion plate 47, and the magnetic directions of the two sets of magnetic blocks 48 are opposite. At this time, the two sets of magnetic blocks 48 attract each other under the action of magnetic attraction. Under the action of magnetic attraction of the magnetic blocks 48, the expansion plate 47 will bend into a U-shaped structure, and the material will be absorbed. The receiving trough 46 supports the push plate 50 through the rotating shaft 49. During the inward contraction of the expansion plate 47, the push plate 50 is driven to rotate around the rotating shaft 49, thereby causing the push plate 50 to disengage from the outer surface of the sealing plate 44 and keeping the sealing plate 44 in a continuous rotating state. When the metering table 13 detects that the mass of the soft cylinder 14 has reached the preset value, the control system controls the magnetic block 48 to be de-energized. The expansion plate 47 has a C-shaped structure and is made of elastic material. At this time, the expansion plate 47 moves in the opposite direction to reset under its own elastic force, thereby pushing the push plate 50 to rotate upward. There are two sets of receiving troughs 46 and expansion plates 47, which are symmetrically distributed. When the push plate 50 moves to a horizontal state, the push plate 50 moves between the two sets of sealing plates 44. The push plate 50 can limit the sealing plate 44, thereby preventing the sealing plate 44 from moving further, so as to ensure the sealing effect of the sealing plate 44 on the filling tube 37. While improving the material filling accuracy, it can also effectively improve the sensitivity and flexibility of the sealing component.

[0026] Specifically, such as Figure 3 and Figure 5 As shown, a metering component is provided inside the storage tube 24. The metering component includes a support plate 27 fixedly connected to the inner surface of the storage tube 24. A sliding sleeve 30 is fixedly connected to the upper outer surface of the support plate 27. The storage tube 24 supports the sliding sleeve 30 through the support plate 27. A sliding rod 34 is slidably connected to the inner surface of the sliding sleeve 30. The sliding sleeve 30 is used to support the sliding rod 34, so that the sliding rod 34 can slide linearly inside the sliding sleeve 30. An elastic sleeve 28 is fixedly connected to the upper end of the sliding rod 34. The sliding rod 34 is used to support the elastic sleeve 28. A magnetic seat 33 is slidably connected to the outer surface of the sliding sleeve 30. A hinge rod 29 is hinged between the magnetic seat 33 and the sliding sleeve 30. An electromagnetic ring 31 is fixedly connected to the outer surface of the sliding sleeve 30.

[0027] A spring 32 is fixedly connected to the lower outer surface of the slide rod 34. The lower end of the spring 32 is fixedly connected to the upper outer surface of the support plate 27. The spring 32 provides elastic support for the slide rod 34. A cavity 35 is embedded in the lower outer surface of the slide rod 34. A pressure valve 36 is provided on the inner surface of the cavity 35. A deformation groove 38 is embedded in the lower outer surface of the elastic sleeve 28. The deformation groove 38 is annular.

[0028] By adopting the above technical solution, an air pipe 20 is provided on the upper side of the guide pipe 19, and a pressure relief pipe 25 is provided on the outer surface of the upper end of the storage pipe 24. After the material enters the guide pipe 19 through the feed pipe 18 under pressure, the air pipe 20 will inject an appropriate amount of gas into the guide pipe 19. The pressure of the gas will push the paste material downward inside the guide pipe 19, thereby improving the material filling efficiency to a certain extent. After the gas pushes the material into the storage pipe 24, the gas will be discharged outward through the pressure relief pipe 25 on the upper side of the storage pipe 24, thereby ensuring the stability of the pressure inside the storage pipe 24. After the material enters the storage box, it will fall into the elastic sleeve. On the upper side of 28, the elastic sleeve 28 can support and lift the material. The magnetic seat 33 is hinged to the lower side of the elastic sleeve 28 via hinge rods 29. The number of hinge rods 29 is several and they are arranged in a ring array, which can improve the load-bearing capacity of the elastic sleeve 28 to a certain extent. As the material on the upper side of the elastic sleeve 28 gradually increases, the elastic sleeve 28 and the sliding rod 34 will gradually move downward under the action of the material's gravity. During the downward movement of the sliding rod 34, the spring 32 will be compressed. At this time, the gas pressure between the sliding rod 34 and the sliding sleeve 30 will gradually increase. Under the action of pressure, the gas will enter the cavity 35 through the pressure valve 36. When the gas pressure reaches the pressure valve... When the threshold value is 36, the filling machine control system guides the electromagnetic ring 31, causing it to magnetically attract the magnetic seat 33. Under this magnetic attraction, the magnetic seat 33 moves downwards onto the surface of the electromagnetic ring 31. During this movement, the magnetic seat 33 pulls the elastic sleeve 28 via the hinge rod 29, causing it to contract inwards from the deformation groove 38. At this time, the paste-like material on the upper side of the elastic sleeve 28 falls downwards between the elastic sleeve 28 and the storage tube 24. After the elastic sleeve 28 has contracted for a period of time, the filling machine control system changes the magnetic direction of the electromagnetic ring 31. The magnetic seat 33 then moves downwards under the magnetic repulsion of the electromagnetic ring 31. During the upward movement of 33, the elastic sleeve 28 is opened by the hinge rod 29, so that the edge of the elastic sleeve 28 contacts the inner wall of the storage tube 24. Under the elastic force of the spring 32, the slide rod 34 and the elastic sleeve 28 move upward and reset, so that the material can continue to be stored. By setting a quantitative component, the quantitative conveying of the material is achieved by the deformation of the elastic sleeve 28. This not only effectively improves the filling accuracy of the material, but also keeps the amount of material inside the filling tube 37 within an appropriate range. This reduces the risk of excessive filling pressure caused by too much material in the filling tube 37, and thus reduces the impact of filling pressure fluctuations on filling accuracy.

[0029] Specifically, such as Figure 5 and Figure 7As shown, a scraping assembly is provided on the upper side of the elastic sleeve 28. The scraping assembly includes a spiral sleeve 39 rotatably connected to the upper side of the elastic sleeve 28. A support plate 26 is fixedly connected to the lower side of the inner surface of the guide tube 19. A reciprocating screw 51 is fixedly connected to the outer surface of the lower end of the support plate 26. The support plate 26 is used to traction and support the reciprocating screw 51. The outer surface of the reciprocating screw 51 is helically connected to the spiral sleeve 39. An installation groove 40 is embedded in the outer surface of the spiral sleeve 39. A movable pin 42 is fixedly connected to the inner surface of the installation groove 40. A scraper 41 is rotatably connected to the outer surface of the movable pin 42. The spiral sleeve 39 is fixedly supported by the movable pin 42 through the installation groove 40. The scraper 41 is rotatably connected to the movable pin 42 and can rotate with the movable pin 42 as the fulcrum. The lower outer surface of the scraper 41 is in rotatable contact with the upper side of the elastic sleeve 28.

[0030] By adopting the above technical solution, the elastic sleeve 28 moves downward, which drives the spiral sleeve 39 to move downward synchronously. The spiral sleeve 39 is connected to the reciprocating screw 51 by a spiral drive. During the downward movement, the spiral sleeve 39 rotates. During the movement of the spiral sleeve 39, the scraper 41 rotates synchronously through the spiral sleeve 39. During the movement, the scraper 41 scrapes the paste-like material on the surface of the elastic sleeve 28, thereby accelerating the falling off of the material on the surface of the elastic sleeve 28. The scraper 41 can rotate at a certain angle, so that the scraper 41 always keeps in contact with the surface of the elastic sleeve 28 under the action of gravity, thereby further improving the scraping effect on the material.

[0031] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, a support rod 15 is fixedly connected to the upper outer surface of the frame 11, a feeding part 16 is fixedly connected to the upper outer surface of the support rod 15, a feeding pipe 18 is fixedly connected to the outer surface of the feeding part 16, and the feeding pipe 18 is internally connected to the guide pipe 19.

[0032] A motor 21 is fixedly connected to the outer surface of the rear end of the feeding section 16. A drive shaft 22 is fixedly connected to the front end of the output shaft of the motor 21. A feeding block 23 is fixedly connected to the outer surface of the drive shaft 22. The feeding block 23 is in rotatable contact with the inner surface of the feeding section 16. A conveying component 17 is fixedly connected to the upper side of the outer surface of the feeding section 16.

[0033] The pressure relief pipes 25 are arranged in several groups in a ring array, and the metering stations 13 are arranged in several groups in a ring array.

[0034] By adopting the above technical solution, when the material is being filled, the material to be filled is injected into the inside of the feeding section 16 through the feeding component 17. The motor 21 drives the feeding block 23 to rotate synchronously through the drive shaft 22. A fan-shaped notch is opened on the outer surface of the feeding pipe 18. During the rotation, the feeding block 23 will inject the material into the inside of the feeding pipe 18 through the notch, and then inject it into the guide pipe 19 under pressure through the feeding pipe 18, thereby realizing the continuous injection of the material.

[0035] Working Principle: During operation, the feeding block 23, while rotating, injects material into the feeding pipe 18 through the notch. The material is then pressurized through the feeding pipe 18 and injected into the guide pipe 19. Gas pressure propels the paste-like material downwards within the guide pipe 19. After entering the storage bin, the material falls onto the upper side of the elastic sleeve 28, which supports and lifts it. The magnetic seat 33, under magnetic attraction, moves downwards onto the surface of the electromagnetic ring 31. The movement of the magnetic seat 33 pulls the elastic sleeve 28, causing it to contract inwards from the deformation groove 38. The paste-like material on the upper side of the elastic sleeve 28 falls downwards between the elastic sleeve 28 and the storage pipe 24. The movement of the spiral sleeve 39 drives the scraper 41 to rotate synchronously. The scraper 41 scrapes the paste-like material on the surface of the elastic sleeve 28, accelerating the removal of the paste. When the material falls onto the upper side of the sealing plate 44, the sealing plate 44 will rotate around the pin under the action of the material's gravity. The liquid will flow into the lowermost liquid storage chamber 45 under its own gravity, causing the center of gravity of the four sets of sealing plates 44 to shift downward, thus keeping two sets of sealing plates 44 in a vertical state. At this time, the other two sets of sealing plates 44 will be in horizontal contact with the inner wall of the filling tube 37. The sealing plates 44 can continuously seal the inside of the filling tube 37, effectively reducing the dripping of paste material during the filling gap of the filling equipment. When the metering table 13 detects that the mass of the soft cylinder 14 has reached the preset value, the expansion plate 47 moves in the opposite direction to reset under its own elastic force, thereby pushing the push plate 50 to rotate upward. The push plate 50 can limit the sealing plate 44, thereby preventing the sealing plate 44 from moving further, so as to ensure the sealing effect of the sealing plate 44 on the filling tube 37.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
