Description

Technical Field

[0001] This invention relates to the technical field of shrimp intestine preparation, specifically a method and apparatus for preparing juicy shrimp intestines. Background Technology

[0002] As is widely known, the process of making juicy shrimp sausage involves processing, cleaning, and chopping the shrimp, adding auxiliary ingredients, adjusting the mixing time and frequency using a mixer, and pressing to ensure the shrimp sausage filling is fully saturated with liquid. After being stuffed into sausage casings, it is baked and then enjoyed for its juicy burst.

[0003] For example, the shrimp sausage processing method disclosed in announcement number CN115669883A on February 3, 2023, includes multiple processes such as processing, packaging, and storing shrimp sausages. The shrimp sausage of this invention employs a series of processing steps including raw material handling, impurity removal, cleaning, re-inspection, water retention treatment, cleaning / draining, granulation, pulping, preservation treatment, sausage stuffing, steaming, cooling and segmentation, inner packaging, and quick-freezing. This process produces shrimp sausages with good elasticity, sufficient moisture, and cleanliness, meeting consumer demands for product quality while using minimal additives, ensuring safety and health. Furthermore, in addition to the main processing steps, the packaging, disinfection, and storage processes also include metal detection, outer packaging and cold storage, acceptance / storage of inner packaging materials, disinfection of inner packaging materials, acceptance / storage of outer packaging materials, acceptance and storage of auxiliary materials / additives, and auxiliary material preparation. This allows consumers to obtain healthy and hygienic shrimp sausage products, and the included auxiliary materials facilitate consumer handling and consumption.

[0004] The shortcoming of the existing technology is that when loading the sausage casings onto the filling tube, it needs to be done manually by the staff. The manual loading operation has large differences, and the folds of the sausage casings on the filling tube are prone to accumulation. As a result, when the filling is sprayed out in industrialized rapid filling, too much sausage casing is brought out, which makes it impossible to fill evenly. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for preparing juicy shrimp intestines, thereby solving the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a preparation device for juicy shrimp sausage, comprising a stirring unit and a filling unit, wherein the stirring unit and the filling unit are connected by a pipe fitting, and further comprising: an auxiliary unit, wherein the auxiliary unit comprises a filling tube, the end of the filling tube being connected to the filling port of the filling unit, and a traction ring being slidably sleeved on the filling tube by a guide structure, wherein a suction cup for pulling the sausage casing is provided on the inner side of the traction ring, driving the traction ring to reciprocate on the outer wall of the filling tube, thereby attaching the sausage casing to the outer wall of the filling tube by the suction cup.

[0007] As described above, the traction ring has multiple perforations evenly distributed along its circumferential direction in its middle part, and a suction cup is slidably installed in each of the perforations.

[0008] As described above, an active ring is rotatably mounted on the outer wall of the traction ring, a driven rod is mounted on the outer wall of the active ring, and multiple active grooves are evenly opened on the side wall of the active ring along its circumferential direction. Each suction cup has an active rod mounted at its end, and each active ring is slidably mounted in its corresponding active groove.

[0009] The aforementioned guide structure consists of two arc-shaped panels symmetrical about the axis of the filling tube. The center of each arc-shaped panel coincides with the center of the filling tube. The ends of the two arc-shaped panels closer to the filling unit are connected to the filling tube via a positioning plate, and the ends of the two arc-shaped panels farther from the filling unit are connected via a connecting plate. A driving component is provided on the positioning plate, and a lead screw is installed at the output end of the driving component. The end of the lead screw is rotatably mounted on the connecting plate, and the lead screw is threadedly connected to the traction ring.

[0010] As described above, the connecting plate is provided with a first extrusion plate, and the first extrusion plate has a first extrusion groove.

[0011] As described above, the first extrusion groove is divided into a first straight section and a first triangular section, and the hypotenuse of the first triangular section slopes downward from the end away from the filling unit to the end closer to the filling unit.

[0012] As described above, the positioning plate is provided with a second extrusion plate, and the second extrusion plate has a second extrusion groove.

[0013] As mentioned above, the second extrusion groove is divided into a second straight section and a second triangular section, and the hypotenuse of the second triangular section slopes downward from the end away from the filling unit to the end closer to the filling unit.

[0014] As described above, the hypotenuse of the first triangular portion is parallel to the hypotenuse of the second triangular portion, and the first straight portion is parallel to the second straight portion.

[0015] The beneficial effects of this invention are as follows: through the linear reciprocating motion of the traction ring on the guide structure, the traction ring and the suction cup pull the casing onto the outer wall of the filling tube, eliminating the need for workers to manually put the casing onto the outer wall of the filling tube, and the casing is put on more orderly.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 8 The present invention will now be described in further detail.

[0028] One embodiment of the present invention relates to a preparation apparatus for juicy shrimp sausage, comprising a stirring unit 1 and a filling unit 2, wherein the stirring unit 1 and the filling unit 2 are connected by a pipe fitting, and further comprising:

[0029] The auxiliary unit includes a filling tube 3, the end of which is connected to the filling port of the filling unit 2. A traction ring 5 is slidably sleeved on the filling tube 3 through a guide structure. A suction cup 7 for pulling the casing is provided inside the traction ring 5, driving the traction ring 5 to reciprocate on the outer wall of the filling tube 3. In this way, the casing is sleeved onto the outer wall of the filling tube 3 by the suction cup 7.

[0030] Specifically, mixing unit 1 is a machine used to mix shrimp intestine raw materials. Mixing unit 1 can adjust the mixing time, mixing frequency, and extrusion pressure. The shrimp intestine raw materials are transported into mixing unit 1. By adjusting the mixing time, mixing frequency, and extrusion pressure of mixing unit 1, the shrimp intestine raw materials are fully mixed. Filling unit 2 is a machine used to fill the shrimp intestine raw materials. After mixing the shrimp intestine raw materials by mixing unit 1, they are transported from the pipe to filling unit 2. Filling unit 2 applies a certain filling force, so that the shrimp intestine raw materials are filled into the casing from filling pipe 3. The guide on filling pipe 3... The structure consists of two arc-shaped panels 4, arranged along the axial direction of the filling tube 3. The two arc-shaped panels 4 are positioned on either side above the filling tube 3. Alternatively, guide rods can be used as a guiding mechanism. The two arc-shaped panels 4 pass through a traction ring 5, allowing the traction ring 5 to slide back and forth on the arc-shaped panels 4, guiding the linear motion of the traction ring 5. One end of the arc-shaped panel 4 is fixedly connected to the filling unit 2, ensuring that the centers of the arc-shaped panels 4 and the filling tube 3 coincide. When shrimp intestine filling is required, the worker places the casing onto the end of the filling tube 3 (i.e., the filling section of the filling tube 3). (At the filling position), the driving traction ring 5 slides on the arc panel 4, causing the traction ring 5 to move the casing from the end of the filling tube 3 to the end of the filling unit 2, so that the casing is fitted onto the outer wall of the filling tube 3. By driving the traction ring 5 to slide back and forth on the arc panel 4, the traction ring 5 can repeatedly pull the casing, so that the casing is completely fitted onto the outer wall of the filling tube 3, which can reduce the time for workers to fit the casing. The filling unit 2 is started so that the shrimp intestine raw material is sprayed out from the filling tube 3, so that the shrimp intestine raw material is filled into the casing. When the shrimp intestine raw material is filled into the casing, under the force of the shrimp intestine raw material filling, The casing gradually detaches from the filling tube 3 until the casing is completely filled with shrimp intestine raw material. This ensures that the shrimp intestine raw material is completely filled into the casing. The shortcoming of the prior art is that when the casing is put onto the filling tube 3, it needs to be done manually by the staff. As a result, the folds of the casing on the filling tube 3 are prone to pile up, causing the filling to spray out too much casing during filling. However, in this embodiment, the linear reciprocating motion of the traction ring 5 on the guide structure allows the traction ring 5 and the suction cup 7 to pull the casing onto the outer wall of the filling tube 3, eliminating the need for the staff to manually put the casing onto the outer wall of the filling tube 3.

[0031] Furthermore, the traction ring 5 has multiple perforations evenly distributed along its circumferential direction in its middle part, and a suction cup 7 is slidably installed in each of the perforations; an active ring 8 is rotatably installed on the outer wall of the traction ring 5, a driven rod 9 is installed on the outer wall of the active ring 8, and multiple active grooves 10 are evenly distributed along its circumferential direction on the side wall of the active ring 8, and an active rod 11 is installed at the end of each suction cup 7, and each active ring 8 is slidably installed in its corresponding active groove 10.

[0032] Specifically, when it is necessary to put the casing on the filling tube 3, the worker first puts the end of the casing on the filling tube 3, (1) drives the traction ring 5 to move to the end of the filling tube 3 away from the filling unit 2, until the traction ring 5 slides on the arc panel 4 to the end away from the filling unit 2, pushes the driven rod 9 to drive the active ring 8 to rotate clockwise by a certain angle. Since the active rod 11 is slidably set in the corresponding active groove 10, and since the active groove 10 is set as an inclined arc groove, that is, one end of the arc groove is relatively smaller than the other end. One end is closer to the central axis of the filling tube 3, causing the active groove 10 to drive the active rod 11 to slide along the trajectory of the active groove 10. At the same time, since the suction cup 7 is slidably installed in the perforation, the active ring 8 slides through the active groove 10, driving each active rod 11 to slide closer to the end of the filling tube 3. Each active rod 11 simultaneously drives the suction cup 7 to slide closer to the end of the filling tube 3, so that the suction cup 7 adheres to and abuts against the casing on the surface of the filling tube 3. The traction ring 5 is manually or automatically driven to slide on the arc panel 4 from the end away from the filling unit 2. (1) Move to one end near the filling unit 2, so that the traction ring 5 pulls the casing onto the surface of the filling tube 3 through the suction cup 7; (2) When the traction ring 5 slides on the arc panel 4 to one end near the filling unit 2, push the driven rod 9 to drive the active ring 8 to rotate counterclockwise by a certain angle. Since the active rod 11 is slidably set in the corresponding active groove 10, the active groove 10 drives the active rod 11 to slide along the trajectory of the active groove 10. At the same time, since the suction cup 7 is slidably installed in the perforation, the active ring 8 passes through the active groove 10. By driving each active rod 11 to slide away from the end of the filling tube 3, each active rod 11 simultaneously drives the suction cup 7 to slide away from the end of the filling tube 3, so that the suction cup 7 detaches from the casing on the surface of the filling tube 3. By repeating the above process, the casing can be completely fitted onto the surface of the filling tube 3. At the same time, the traction ring 5 drives the first scanning element 6 to perform linear reciprocating motion on the outer wall of the filling tube 3, so that the first scanning element 6 can perform scanning and detection of the casing, which can effectively detect the damage of the casing and prevent leakage of the casing during shrimp intestine filling.

[0033] Furthermore, the guide structure consists of two arc-shaped panels 4 symmetrical about the axis of the filling tube. The centers of the two arc-shaped panels 4 coincide with the center of the filling tube 3. The ends of the two arc-shaped panels 4 near the filling unit 2 are connected to the filling tube 3 via a positioning plate 12, and the ends of the two arc-shaped panels 4 away from the filling unit 2 are connected via a connecting plate 13. A driving component 14 is provided on the positioning plate 12. A lead screw 15 is installed at the output end of the driving component 14. The end of the lead screw 15 is rotatably mounted on the connecting plate 13, and the lead screw 15 is threadedly connected to the traction ring 5.

[0034] Specifically, when it is necessary to drive the traction ring 5 to perform linear reciprocating motion on the arc panel 4, the drive component 14 (the drive component 14 is a device that can drive the lead screw 15 to reciprocate, preferably a motor) is activated to drive the lead screw 15 to rotate, and the lead screw 15 drives the traction ring 5 to perform linear reciprocating motion on the arc panel 4.

[0035] Furthermore, a first extrusion plate 17 is provided on the connecting plate 13, and a first extrusion groove 18 is formed on the first extrusion plate 17; the first extrusion groove 18 is divided into a first straight portion 181 and a first triangular portion 182, and the hypotenuse of the first triangular portion 182 slopes downward from the end away from the filling unit 2 to the end closer to the filling unit 2; a second extrusion plate 19 is provided on the positioning plate 12, and a second extrusion groove 20 is formed on the second extrusion plate 19; the second extrusion groove 20 is divided into a second straight portion 201 and a second triangular portion 202, and the hypotenuse of the second triangular portion 202 slopes downward from the end away from the filling unit 2 to the end closer to the filling unit 2; the hypotenuse of the first triangular portion 182 and the hypotenuse of the second triangular portion 202 are parallel to each other, and the first straight portion 181 and the second straight portion 201 are parallel to each other.

[0036] Specifically, when it is necessary to put the casing on the filling tube 3, the worker first puts the end of the casing on the filling tube 3, (1) starts the drive component 14 to drive the screw 15 to rotate clockwise, the screw 15 drives the traction ring 5 to move from the end near the filling unit 2 to the end away from the filling unit 2, until the traction ring 5 drives the driven rod 9 on the active ring 8 to press against the first triangular part 182 of the first extrusion groove 18, and continues to drive the traction ring 5 to move away from the filling unit 2. Since the hypotenuse of the first triangular part 182 is inclined downward from the end away from the filling unit 2 to the end near the filling unit 2, and the driven rod 9 moves along the hypotenuse of the first triangular part 182, under the action of the hypotenuse of the first triangular part 182, the driven rod 9 is forced to slide along the hypotenuse of the first triangular part 182, so that the driven rod 9 rotates clockwise by a certain angle. 9 drives the active ring 8 to rotate clockwise by a certain angle until the driven rod 9 slides from the first triangular part 182 into the first straight part 181. At the same time, since the active rod 11 is slidably set in the corresponding active groove 10, and since the active groove 10 is set as an inclined arc groove, the active groove 10 drives the active rod 11 to slide along the trajectory of the active groove 10. At the same time, since the suction cup 7 is slidably installed in the perforation, the active ring 8 drives each active rod 11 to slide towards the end closer to the filling tube 3 through the active groove 10. Each active rod 11 simultaneously drives the suction cup 7 to slide towards the end closer to the filling tube 3, so that the suction cup 7 adsorbs the casing on the surface of the filling tube 3, and drives the traction ring 5 to slide on the arc panel 4 from the end away from the filling unit 2 to the end closer to the filling unit 2, so that the traction ring 5 pulls the casing onto the surface of the filling tube 3 through the suction cup 7.(2) When the traction ring 5 needs to move from the end away from the filling unit 2 to the end closer to the filling unit 2 on the arc panel 4, the drive unit 14 is activated to drive the lead screw 15 to rotate counterclockwise. The lead screw 15 drives the traction ring 5 to move from the end away from the filling unit 2 to the end closer to the filling unit 2 until the traction ring 5 drives the driven rod 9 on the driving ring 8 to press against the second triangular part 202 of the second extrusion groove 20. Continue to drive the traction ring 5 to move closer to the filling unit 2. Since the hypotenuse of the second triangular part 202 is inclined downward from the end away from the filling unit 2 to the end closer to the filling unit 2, and the driven rod 9 moves along the hypotenuse of the second triangular part 202, under the action of the hypotenuse of the second triangular part 202, the driven rod 9 is forced to slide along the hypotenuse of the second triangular part 202, so that the driven rod 9 rotates counterclockwise by a certain angle. The driven rod 9 drives the driving ring 8 to rotate counterclockwise. At a certain angle, the driven rod 9 slides from the second triangular part 202 into the second straight part 201. Simultaneously, since the active rod 11 is slidably positioned within its corresponding active groove 10, the active groove 10 drives the active rod 11 to slide along its trajectory. Simultaneously, since the suction cup 7 is slidably installed within the perforation, the active ring 8 slides through the active groove 10, driving each active rod 11 to slide away from the end of the filling tube 3. Each active rod 11 simultaneously drives the suction cup 7 to slide away from the end of the filling tube 3, causing the suction cup 7 to detach from the casing on the surface of the filling tube 3. Repeating this process ensures the casing is completely fitted onto the surface of the filling tube 3. Simultaneously, the traction ring 5 drives the first scanning element 6 to perform linear reciprocating motion on the outer wall of the filling tube 3, enabling the first scanning element 6 to scan and inspect the casing, effectively detecting any damage and preventing leakage during shrimp intestine filling.

[0037] Furthermore, a plurality of grooves 21 are evenly provided on the inner wall of the active ring 8 along its circumferential direction. Each groove 21 has a slidingly installed a retaining block 22. Each retaining block 22 and the inner wall of its corresponding groove 21 are connected by a first elastic element 23. Each retaining block 22 abuts against the outer wall of the traction ring 5.

[0038] Specifically, since the first elastic element 23 (which is a component capable of telescopic return, preferably a spring) provides a certain elastic force to the abutting block 22, each abutting block 22 is pressed against the outer wall of the traction ring 5 under the elastic force of the first elastic element 23, so that the active ring 8 will not rotate freely on the outer wall of the traction ring 5, but is subjected to the frictional force between the abutting block 22 and the traction ring 5. However, since the first pressing groove 18 and the second pressing groove 20 exert a large pressing force on the driven rod 9, the active ring 8 is forced to rotate on the outer wall of the traction ring 5. That is, when the driven rod 9 is not subjected to the pressing force of the first pressing groove 18 and the second pressing groove 20, the active ring 8 will not rotate on the traction ring 5.

[0039] In another embodiment of the present invention, a positioning ring 24 is connected to the end of the connecting plate 13. The positioning ring 24 has a plurality of through holes evenly distributed along its circumferential direction. A sliding rod 25 is slidably installed in each of the through holes. An arc-shaped plate 26 is installed inside each of the sliding rods 25. A return plate 27 is installed on the outer wall of each sliding rod 25 on the side away from the traction ring 5. A second elastic joint is connected between each return plate 27 and the outer wall of the positioning ring 24. The positioning ring 24 is connected to the positioning ring 24. A pushing ring 29 is slidably installed on the outer wall of the positioning ring 24. Each sliding rod 25 and the inner wall of the pushing ring 29 are wedge-shaped and abut against each other. The pushing ring 29 and the inner wall of the positioning ring 24 are connected by a plurality of third elastic elements 30 evenly arranged along their circumferential direction. A plurality of pushing rods 31 are evenly arranged along their circumferential direction on the side wall of the active ring 8 near the positioning ring 24. Each pushing rod 31 is used in conjunction with the active ring 8.

[0040] Specifically, during the movement of the traction ring 5 on the arc panel 4 from the end closest to the filling unit 2 to the end furthest from the filling unit 2, when the traction ring 5 drives the driven rod 9 on the active ring 8 to abut against the first extrusion groove 18, the active ring 8 drives the propulsion rod 31 to press against the outer wall of the propulsion ring 29, continuing to drive the traction ring 5 to move towards the end furthest from the filling unit 2. The traction ring 5, through the active ring 8 driving the propulsion rod 31, pushes the propulsion ring 29 towards the end furthest from the filling tube 3. The propulsion ring 29 then moves against the third elastic element. The third elastic element 30 (which is a component capable of telescopic return, preferably a spring) is compressed, causing the third elastic element 30 to be in a compressed state. Because the sliding rods 25 and the inner walls of the pushing ring 29 are wedge-shaped and abut against each other, the pushing ring 29 pushes the sliding rods 25 to slide towards one end of the positioning ring 24. Since the sliding rods 25 are equipped with a return plate 27 and a second elastic element 28, when the sliding rods 25 slide towards one end of the positioning ring 24, the return plate 27 compresses the second elastic element 28 (which is a component capable of telescopic return, preferably a spring). The component capable of telescopic retraction and reset (preferably a spring) performs the extrusion operation. Each sliding rod 25 synchronously drives each arc-shaped plate 26 to synchronously retract towards one end of the positioning ring 24, causing each arc-shaped plate 26 to press the casing tightly against the end of the filling tube 3. At this point, the wedge-shaped engagement between each sliding rod 25 and the inner wall of the pushing ring 29 ends (at this time, the traction ring 5 drives the driven rod 9 on the active ring 8 to slide along the trajectory of the first extrusion groove 18 to the middle of the first triangular portion 182, and the suction cup 7 has not yet adhered to the casing). That is, the driving continues at this point. When the traction ring 5 slides away from the filling unit 2, the pushing ring 29 will not push the sliding rods 25 to retract towards the inside of the positioning ring 24. At this time, shrimp intestine filling can be carried out. The filling unit 2 is started so that the shrimp intestine raw material is sprayed out from the filling tube 3, so that the shrimp intestine raw material is filled into the casing. Because the arc plates 26 gather and converge the part of the opening of the filling tube 3, the opening position of the casing is smaller, so that the opening position of the casing can be completely filled with shrimp intestine raw material, reducing the probability of the casing opening position not being filled with shrimp intestine raw material.

[0041] In another embodiment of the present invention, the end of the filling tube 3 is an inclined tip, and the side of each of the arc plates 26 near the filling tube 3 is an inclined arc surface. A plurality of first balls 32 are rotatably mounted on the inclined arc surface of each of the arc plates 26. Each of the first balls 32 cooperates with the inclined tip of the filling tube 3. A slot 33 is opened on the side of each of the arc plates 26 away from the filling tube 3. A gathering plate 34 is slidably mounted in each of the slots 33. Each gathering plate 34 and the inner wall of its corresponding slot 33 are connected by a fourth elastic member 35. A plurality of second balls 36 are rotatably mounted on the end face of each gathering plate 34. The second balls 36 on the end face of each gathering plate 34 and the first balls 32 on each of the arc plates 26 are inclined and gathered from the end near the filling tube 3 to the end away from the filling tube 3.

[0042] Specifically, when the traction ring 5 drives the propulsion ring 31 via the active ring 8 to push the propulsion ring 29 away from the filling tube 3, the wedge-shaped engagement between each sliding rod 25 and the inner wall of the propulsion ring 29 causes the propulsion ring 29 to push each sliding rod 25 to slide into the inner end of the positioning ring 24. Simultaneously, each sliding rod 25 drives each arc-shaped plate 26 to retract into the inner end of the positioning ring 24, causing each arc-shaped plate 26 to press the casing tightly against the end of the filling tube 3. At this point, the wedge-shaped engagement between each sliding rod 25 and the inner wall of the propulsion ring 29 ends (at this time, the traction ring 5 drives the active ring 8 to move away from the filling tube 3). The driven rod 9 slides along the trajectory of the first extrusion groove 18 to the middle of the first triangular portion 182 (before the suction cup 7 is attracted to the casing). That is, when the traction ring 5 continues to slide away from the filling unit 2, the pushing ring 29 will not push the sliding rods 25 to retract into the positioning ring 24. At this time, the first ball 32 is pressed against the inclined tip of the filling tube 3 (that is, there is a casing between the inclined tip of the filling tube 3 and the first ball 32). Since the arc plates 26 gather and converge the part of the filling tube 3 opening, the arc plates 26 drive the gathering plate 34 and the second ball 36 to fill. One end of the tube 3 is narrowed, causing the narrowing plate 34 and the second ball bearing 36 to converge and gather the inclined tip of the filling tube 3. At this time, shrimp intestines can be filled. The filling unit 2 is activated, causing the shrimp intestine material to spray out from the filling tube 3, filling the casing with the shrimp intestine material. When the filling unit 2 fills the shrimp intestine material, the shrimp intestine material can drive the casing to detach from the filling tube 3. Since the casing is located between the first ball bearing 32 and the inclined tip of the filling tube 3, the casing is subjected to a certain clamping force from the first ball bearing 32. When the casing detaches from the filling tube 3, it is subjected to the clamping force from the first ball bearing 32, so that the shrimp intestine material filled in the casing is contained within the casing. The casing is more fully loaded, and when the traction ring 5 and suction cup 7 put the casing onto the filling tube 3, the casing will also be subjected to the clamping force of the first ball 32, so that the traction of the casing is subjected to a certain clamping force of the first ball 32. During the process of putting the casing onto the filling tube 3, the first ball 32 performs a certain leveling treatment on the casing, making the casing more even. When the casing is filled with shrimp intestine raw material, the filled casing passes over the surface of the gathering plate 34 and the second ball 36, so that the gathering plate 34 and the second ball 36 perform a certain leveling treatment on the casing filled with shrimp intestine raw material, achieving the flatness of shrimp intestine filling.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

In this way, the casing is sleeved onto the outer wall of the filling tube by the suction cup. The traction ring has multiple holes evenly distributed around its circumference in the middle, and a suction cup is slidably installed in each hole. An active ring is rotatably mounted on the outer wall of the traction ring, a driven rod is mounted on the outer wall of the active ring, and multiple active grooves are evenly opened along the circumferential direction on the side wall of the active ring. An active rod is installed at the end of each suction cup, and each active ring is slidably mounted in its corresponding active groove. The guide structure consists of two arc panels symmetrical about the axis of the filling tube. The center of each arc panel coincides with the center of the filling tube. The ends of the two arc panels closer to the filling unit are connected to the filling tube via a positioning plate, and the ends of the two arc panels farther from the filling unit are connected via a connecting plate. A driving component is provided on the positioning plate, and a lead screw is installed at the output end of the driving component. The end of the lead screw is rotatably mounted on the connecting plate, and the lead screw is threadedly connected to the traction ring. The connecting plate is provided with a first extrusion plate, and a first extrusion groove is formed on the first extrusion plate; The first extrusion groove is divided into a first straight section and a first triangular section. The hypotenuse of the first triangular section slopes downward from the end away from the filling unit to the end closer to the filling unit. The positioning plate is provided with a second extrusion plate, and a second extrusion groove is formed on the second extrusion plate; The second extrusion groove is divided into a second straight section and a second triangular section. The hypotenuse of the second triangular section slopes downward from the end away from the filling unit to the end closer to the filling unit. The hypotenuse of the first triangular portion is parallel to the hypotenuse of the second triangular portion, and the first straight portion is parallel to the second straight portion; Multiple grooves are evenly formed on the inner wall of the active ring along its circumferential direction. A clamping block is slidably installed in each groove. Each clamping block and the inner wall of its corresponding groove are connected by a first elastic element. Each clamping block abuts against the outer wall of the traction ring.
