Description

Technical Field

[0001] This invention belongs to the field of edible oil production and bottling technology, specifically relating to an intelligent regulating edible oil bottling equipment to prevent oil leakage. Background Technology

[0002] Edible oil filling equipment is a core technological tool in the edible oil production and packaging process. Its basic function is to quantitatively inject refined edible oil into packaging containers according to preset capacity specifications. It is widely used in large and medium-sized edible oil refineries, grain and oil processing enterprises, and food packaging contract manufacturers, covering various specifications from medium-sized catering packages to small household packages. With increasingly stringent food safety standards and rising consumer demands for packaging quality, modern edible oil filling equipment must not only meet the requirements of high-speed, high-precision quantitative filling, but also ensure the cleanliness and purity of the oil during the filling process, while possessing excellent operational stability and reliability.

[0003] In existing edible oil filling production technology, empty oil drums are transported sequentially to the filling station by a conveyor belt. When the drums reach the preset filling position, the conveyor belt stops running or the drums are stopped directly below the filling head by a stop mechanism. Then, the filling head descends vertically under the action of a lifting cylinder or screw drive mechanism, and its oil outlet is accurately inserted into the drum opening. The quantitative filling system opens the valve and injects edible oil into the drum according to the preset capacity. During the oil filling process, the filling head can be gradually raised according to the liquid level feedback to adapt to the rise of the liquid level in the drum. After the set filling volume is reached, the valve closes, the filling head rises back to its original position and leaves the drum opening, the conveyor belt restarts to remove the filled oil drums, and at the same time, subsequent empty drums enter the filling station, and so on.

[0004] In continuous operation, existing edible oil filling equipment is affected by conveyor belt vibration, start-stop inertia, and barrel manufacturing tolerances. When the oil barrel arrives at the filling station, it is difficult for the barrel opening axis to automatically and accurately align with the oil outlet of the filling head. This causes the filling head to easily collide and deviate when inserted, resulting in splashing and oil leakage. At the same time, the oil outlet of the traditional filling head is directly exposed to the outside after the filling is completed and the oil is removed from the barrel. The oil at the outlet and inside the pipe is easily dripped onto the conveyor belt and the outer wall of the oil barrel under the action of gravity, which not only wastes oil but also continuously pollutes the production environment.

[0005] Therefore, the present invention provides an intelligent regulating edible oil filling device to prevent oil leakage. Summary of the Invention

[0009] Preferably, the positioning assembly includes a movable part that is slidably connected to the outer wall of the oil inlet pipe. An outer insertion rod is symmetrically fixedly connected to the top of the movable part, and a connector is fixedly connected to the top of the outer insertion rod.

[0010] Preferably, side connecting blocks are fixedly connected to both sides of the oil delivery box, the outer wall of the inner insertion rod is inserted into the inside of the side connecting block, and a spring is fixedly connected to the bottom of each side connecting block. The end of the spring away from the side connecting block is fixedly connected to the top of the movable part.

[0011] Preferably, the adjustment assembly further includes two transverse slides, which are fixedly connected to the two side walls of the conveyor. Each transverse slide has a movable block slidably connected to its inner wall. The upper side of each movable block is fixedly connected to the bottom of the clamping plate. Movable components are provided on both sides of the movable block to drive it to slide along the inner wall of the transverse slide.

[0012] Preferably, the moving component includes a second connector, which is fixedly connected to one side of the lifting block. A fixed frame plate is symmetrically fixedly connected to the bottom of the second connector. A fixed rod is fixedly connected to one side of each fixed frame plate. A wedge block 2 is fixedly connected to one side of each fixed rod. A resisting plate is fixedly connected above each wedge block 2. A wedge block 1 is fixedly connected to both sides of the moving block. The wedge block 1 and the wedge block 2 correspond to each other and cooperate with each other. A spring 2 is fixedly connected between the moving block and the inner wall of the transverse slide.

[0013] Preferably, the correction assembly includes two dual-axis bearing seats, which are respectively fixedly connected to one side of the clamping plate. One dual-axis bearing seat has a fork plate 1 fixedly connected to the outer wall of each of the two shafts, and the other dual-axis bearing seat has a fork plate 2 fixedly connected to the outer wall of each of the two shafts. A gathering assembly that drives the shafts of the dual-axis bearing seats to rotate is provided on one side of the clamping plate.

[0014] Preferably, each gathering component includes multiple eccentric parts, which are respectively fixedly connected to the outer walls of both ends of the double-shaft bearing seat shaft, and connecting ropes are fixedly connected to the outer walls of each eccentric part.

[0015] Preferably, a fixed seat is fixedly connected to both sides of the transverse slide, and a rope loop is fixedly connected above each fixed seat. The end of the connecting rope away from the eccentric part is sleeved on the outer wall of the rope loop.

[0016] Preferably, a torsion spring is fixedly connected to one side of both fork plate one and fork plate two, and the end of the torsion spring away from fork plate one and fork plate two is fixedly connected to the outer wall of the dual-shaft bearing seat.

[0017] The beneficial effects of this invention are as follows: 1. The intelligent adjustable edible oil filling equipment for preventing oil leakage of the present invention, through the coordinated linkage of the inclined surfaces of wedge block two and wedge block one in the adjustment component, converts the vertical downward force of the lifting block into the horizontal clamping force of the clamping plate, drives the clamping plates on both sides to move closer to each other and perform lateral centering positioning of the oil drum. At the same time, the limiting effect of the resisting plate makes the clamping plate maintain a constant position after completing the centering positioning, avoiding the squeezing deformation of the thin-walled oil drum due to excessive clamping force, and effectively compensating for the lateral displacement deviation caused by conveyor belt vibration and barrel manufacturing tolerance.

[0018] 2. The intelligent adjustable edible oil filling equipment for preventing oil leakage described in this invention uses a straightening component where fork plate one and fork plate two converge towards the center under the drive of the converging component, forming a surrounding limiting structure for the opening of the oil drum. Based on the horizontal centering positioning completed by the clamping plate, the opening of the drum is further precisely aligned longitudinally, so that the axis of the opening of the drum is accurately aligned with the axis of the oil inlet pipe outlet. This eliminates the longitudinal position deviation of the oil drum caused by the inertia of the conveyor belt starting and stopping, fundamentally preventing the filling splash and oil leakage problems caused by the offset of the opening, and significantly improving the filling accuracy and production yield.

[0019] 3. The intelligent adjustable edible oil filling equipment for preventing oil leakage described in this invention, through the sealing assembly, when the oil inlet pipe descends and inserts into the barrel opening, the movable part is blocked by the top of the barrel opening and slides upward relative to the oil inlet pipe, causing the blocking block to retract into the funnel and automatically open the filling channel. When the oil inlet pipe rises and exits the barrel opening, the spring releases its elastic force and pushes the movable part downward, so that the blocking block restores the tight seal on the outlet end before the oil inlet pipe completely leaves the barrel opening. This achieves pre-flow interruption and sealing before pipe removal, effectively preventing the problem of residual oil inside the oil inlet pipe dripping onto the conveyor belt and the outer wall of the oil barrel after leaving the barrel opening, avoiding oil waste and environmental pollution, and ensuring the cleanliness of the filling operation.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 10 As shown, the present invention provides a technical solution: an intelligent regulating edible oil filling device to prevent oil leakage, comprising a conveyor 1, an oil delivery box 4 disposed directly above the conveyor 1, an oil inlet pipe 5 fixedly connected to the bottom of the oil delivery box 4, lifting blocks 6 fixedly connected to both sides of the oil delivery box 4, mounting frames 9 fixedly connected to both sides of the conveyor 1, the lifting blocks 6 being slidably connected to the inner walls of the mounting frames 9 respectively, telescopic rods 8 fixedly connected to the inner walls of the mounting frames 9, the output ends of the telescopic rods 8 being fixedly connected to the bottom of the lifting blocks 6, and a corrugated pipe fixedly connected to the top of the oil delivery box 4. 3. A filling cylinder 2 is fixedly connected to the top of the corrugated pipe 3. The filling cylinder 2 is fixedly connected to the top of the vertical slide 7. A sealing assembly is provided inside the oil inlet pipe 5. The sealing assembly includes a liftable blocking block 12. The blocking block 12 can dynamically block the outlet end of the oil inlet pipe 5 by lifting and moving. Adjustment assemblies are provided on both sides of the conveyor 1. The adjustment assembly includes two clamping plates 10 that can move relative to each other. The clamping plates 10 can center the oil drum by moving relative to each other. A alignment assembly is provided on one side of the clamping plate 10 to align the mouth of the oil drum.

[0025] During operation: When the oil drum is conveyed by conveyor 1 to the center of the filling station, due to the vibration of the conveyor belt, the inertial force of starting and stopping, and the manufacturing tolerance of the drum itself, the oil drum will have a two-dimensional positional deviation in the horizontal plane: First, the center line of the drum will shift laterally relative to the center line of the conveyor belt (i.e., it will not be centered left and right); Second, due to the inertia generated by the start and stop of the conveyor belt, the oil drum will have overshoot or lag in feeding, that is, longitudinal displacement error will occur along the conveying direction (i.e., the actual stopping position is forward or backward relative to the filling reference position). The superposition of the above two deviations makes it impossible for the axis of the drum opening to automatically coincide with the axis of the outlet of the oil inlet pipe 5. To solve the above problems, when the oil drum arrives at the filling station, the telescopic rod 8 is first retracted, driving the lifting block 6 to slide downwards along the inner wall of the mounting frame 9. This causes the oil delivery box 4 and the oil inlet pipe 5 to descend vertically as a whole, gradually approaching the opening of the oil drum below. During the descent of the oil delivery box 4, the adjusting components move synchronously, and the two clamping plates 10 move closer to each other. By applying symmetrical thrust to the two side walls of the oil drum, the oil drum is forced to be pushed laterally (X-direction) to the center line of the conveyor belt, achieving the centering positioning of the drum. At the same time, the alignment component set on one side of the clamping plate 10 moves synchronously to adjust the left and right position deviation of the oil drum, eliminating the horizontal deviation. Based on the deviation, the barrel opening is precisely aligned in the front-to-back direction, so that the center of the barrel opening is precisely aligned with the bottom of the oil inlet pipe 5 outlet. Through the synergistic effect of the centering positioning of the clamping plate 10 and the barrel opening alignment of the alignment component, it can effectively compensate for the lateral displacement and longitudinal feed error caused by vibration, inertia and manufacturing tolerances under the continuous filling condition of the conveyor belt without stopping. Finally, the barrel opening can still be forcibly corrected to the ideal centering position of the filling head, thus providing a precise alignment basis for the subsequent insertion of the oil inlet pipe 5 and oil injection action, eliminating the oil leakage problem caused by barrel opening deviation from the root, and significantly improving filling accuracy and production yield. On the other hand, after the oil inlet pipe 5 is lowered and inserted into the barrel opening after the alignment component completes the barrel opening alignment and completes the quantitative filling operation, since some edible oil may still remain in the oil inlet pipe 5 and the internal cavity of the oil delivery box 4, if the oil inlet pipe 5 is directly exposed to the outside when it leaves the barrel opening, as the oil barrel continues to be conveyed forward, the residual oil is very likely to drip from the outlet end of the oil inlet pipe 5 onto the surface of the conveyor belt of the conveyor 1 under the action of gravity. This not only wastes oil, but also contaminates the conveyor belt and the outer wall of the subsequent oil barrel, seriously affecting the cleanliness of the production environment and the filling quality. To address this issue, in the initial state, the plug 12 remains tightly sealed at the outlet end of the oil inlet pipe 5, ensuring that the internal cavity of the oil inlet pipe 5 is isolated from the outside and preventing accidental oil leakage. When the oil delivery box 4 is driven by the telescopic rod 8 to descend as a whole, bringing the oil inlet pipe 5 close to the mouth of the oil drum, the plug 12 remains sealed until the outlet end of the oil inlet pipe 5 is inserted into the drum mouth, ensuring that no oil drips during the descent. As the oil inlet pipe 5 continues to move downward, its outlet end begins to extend into the oil drum mouth and gradually inserts to the preset depth inside the drum. The sealing component keeps the plug 12 stationary, preventing it from following the oil inlet pipe 5 into the drum mouth. Meanwhile, the oil inlet pipe 5 continues to move downward relative to the plug 12. This relative movement causes the plug 12 to gradually detach from the oil inlet pipe. At the outlet end of pipe 5, the seal is released, and at this time, the outlet end of the oil inlet pipe 5 is fully inserted into the oil drum. The filling channel is opened, and edible oil can be smoothly injected into the oil drum through the filling cylinder 2, corrugated pipe 3, oil delivery box 4, and oil inlet pipe 5. When the filling operation is completed, the telescopic rod 8 extends in the opposite direction, driving the oil delivery box 4 and oil inlet pipe 5 to rise and reset as a whole. During this process, the oil inlet pipe 5 moves upward relative to the blocking block 12, so that the blocking block 12 re-seals the outlet end of the oil inlet pipe 5. The seal is restored before the oil inlet pipe 5 completely leaves the drum opening, ensuring that the outlet end of the oil inlet pipe 5 is always under the sealed protection of the blocking block 12 during the entire rising and moving process after leaving the drum opening. This effectively prevents the leakage of residual oil in the pipe and solves the problem of dripping oil pollution and oil waste from the root.

[0026] like Figures 3 to 4 As shown, the sealing assembly also includes an inner rod 11, which is fixedly connected to the top of the blocking block 12. The top end of the inner rod 11 is inserted into the top inner wall of the oil delivery box 4. The center outer wall of the oil inlet pipe 5 is fixedly connected to a funnel 13. The outside of the oil delivery box 4 is provided with a locking assembly to restrict the movement of the blocking block 12.

[0027] During operation: The maximum radius of the blocking block 12 is set to be the same as the radius of the oil inlet pipe 5, while the radius of the funnel 13 is much larger than the maximum radius of the blocking block 12. When the oil inlet pipe 5 is driven by the telescopic rod 8 to descend and approach the barrel opening, the blocking block 12 moves down synchronously with the oil inlet pipe 5 under the traction of the inner insertion rod 11, and its bottom end is always tightly sealed at the outlet end of the oil inlet pipe 5 to ensure that no oil drips during the descent. When the outlet end of the oil inlet pipe 5 begins to extend into the barrel opening, the locking component applies a limiting effect to the blocking block 12, preventing it from continuing to descend with the oil inlet pipe 5. As the oil inlet pipe 5 continues to be inserted downwards, its outlet end gradually extends into the inside of the barrel opening, while the blocking block 12 is limited by the locking component. When the oil inlet pipe 5 remains stationary, it slides downward relative to the blocking block 12. The blocking block 12 gradually retracts into the oil inlet pipe 5 until it is completely within the accommodating space of the funnel 13. The outlet end of the oil inlet pipe 5 is fully opened, and the filling channel is unobstructed. In this state, since the radius of the funnel 13 is much larger than the maximum radius of the blocking block 12, a sufficient oil passage gap is formed between the blocking block 12 and the inner wall of the funnel 13. Edible oil can flow smoothly into the oil drum through this gap to complete the filling. After filling is completed, the oil inlet pipe 5 rises and resets, the locking component releases the limit and assists the blocking block 12 to move downward relative to the oil inlet pipe 5, so that it re-seals the outlet end of the oil inlet pipe 5 and restores the sealing state.

[0028] like Figures 3 to 4 As shown, the positioning assembly includes a movable part 14, which is slidably connected to the outer wall of the oil inlet pipe 5. An outer insertion rod 16 is symmetrically fixedly connected to the top of the movable part 14, and a connector 17 is fixedly connected to the top of the outer insertion rod 16. The inner wall of the connector 17 is fixedly connected to the top of the inner insertion rod 11.

[0029] During operation: In the initial state, the bottom end of the movable part 14 is flush with the bottom end of the oil inlet pipe 5. At this time, the blocking block 12 seals the outlet end of the oil inlet pipe 5. When the telescopic rod 8 drives the oil box 4 and the oil inlet pipe 5 to descend as a whole, and the bottom end of the oil inlet pipe 5 just touches the upper surface of the oil drum opening but has not yet been inserted, the bottom end of the movable part 14 just abuts against the top of the drum opening. As the oil inlet pipe 5 continues to move downward and gradually inserts into the inner wall of the drum opening, the movable part 14 is blocked by the top of the drum opening and cannot continue to advance. As the oil pipe 5 descends synchronously, the movable part 14 slides upward along its outer wall relative to the oil inlet pipe 5. Therefore, the upward movement of the movable part 14 relative to the oil inlet pipe 5 will synchronously drive the inner insert rod 11 and the blocking block 12 to move upward relative to the oil inlet pipe 5. This causes the blocking block 12 to gradually detach from the outlet end of the oil inlet pipe 5 and retract into the funnel 13, releasing the seal. The outlet end of the oil inlet pipe 5 is then fully opened, and the edible oil can be smoothly injected into the oil container through the oil passage gap between the funnel 13 and the blocking block 12.

[0030] like Figures 3 to 4As shown, side connecting blocks 15 are fixedly connected to both sides of the oil box 4. The outer wall of the inner insert rod 11 is inserted into the inside of the side connecting block 15. A spring 18 is fixedly connected to the bottom of the side connecting block 15. The end of the spring 18 away from the side connecting block 15 is fixedly connected to the top of the movable part 14.

[0031] During operation: When the bottom end of the oil inlet pipe 5 contacts the barrel opening, the movable part 14 is blocked by the top of the barrel opening and slides upward relative to the oil inlet pipe 5, and the spring 18 is compressed. When the filling operation is completed, the telescopic rod 8 extends in the opposite direction to drive the oil delivery box 4 and the oil inlet pipe 5 to rise and reset as a whole. As the oil inlet pipe 5 gradually exits from the inner wall of the barrel opening, the side connecting block 15 moves upward synchronously with the oil delivery box 4. The elastic force stored when the spring 18 is compressed is gradually released, pushing the movable part 14 to slide downward along the outer wall of the oil inlet pipe 5, and driving the blocking block 12 to move downward synchronously. As the oil inlet pipe 5 gradually exits from the barrel opening, the blocking block 12 gradually re-seals the outlet end of the oil inlet pipe 5. When the oil inlet pipe 5 is completely removed from the barrel opening, the blocking block 12 has completely restored the sealing state of the outlet end of the oil inlet pipe 5, ensuring that no residual oil drips during the entire exit process.

[0032] like Figures 5 to 6 As shown, the adjustment assembly also includes two transverse slides 20, which are fixedly connected to the two side walls of the conveyor 1. Each transverse slide 20 has a movable block 19 slidably connected to its inner wall. The upper side of each movable block 19 is fixedly connected to the bottom of the clamping plate 10. Movable components are provided on both sides of the movable block 19 to drive it to slide along the inner wall of the transverse slide 20.

[0033] During operation: When the lifting block 6 slides down along the inner wall of the vertical slide 7, driving the oil box 4 and the oil inlet pipe 5 to descend as a whole, the moving component moves synchronously, driving the moving block 19 to slide towards each other along the inner wall of the horizontal slide 20. The moving block 19 drives the clamping plate 10 to move synchronously. In the initial state, the distance between the two clamping plates 10 is greater than the maximum width of the oil drum, so as to ensure that the oil drum can enter the filling station without obstruction. As the moving component drives the clamping plates 10 to move towards each other, the two clamping plates 10 gradually approach the oil drum. The distance of their relative movement is set so that the inner wall of the clamping plate 10 abuts against the two side walls of the oil drum. That is, the clamping plate 10 only applies a slight contact force to the oil drum to push the oil drum to the center line of the conveyor belt, without applying excessive clamping force to the two side walls of the oil drum, so as to avoid the thin-walled oil drum being squeezed and deformed due to excessive clamping force.

[0034] like Figures 5 to 6As shown, the moving component includes a second connector 21, which is fixedly connected to one side of the lifting block 6. A fixed frame plate 22 is symmetrically fixedly connected to the bottom of the second connector 21. A fixed rod 26 is fixedly connected to one side of each fixed frame plate 22. A wedge block 24 is fixedly connected to one side of each fixed rod 26. A resisting plate 25 is fixedly connected above each wedge block 24. A wedge block 23 is fixedly connected to both sides of the moving block 19. The wedge block 23 and the wedge block 24 cooperate with each other. A spring 27 is fixedly connected between the moving block 19 and the inner wall of the transverse slide 20.

[0035] During operation: In the initial state, wedge block 24 abuts against one side of wedge block 23, spring 27 is compressed, and the two clamping plates 10 are in a mutually distancing open state with a distance greater than the maximum width of the oil drum to ensure that the oil drum can enter the filling station without obstruction. When the lifting block 6 slides down along the inner wall of the vertical slide 7, the connecting piece 21 and the fixed frame plate 22 drive the wedge block 24 to descend as a whole. As the wedge block 24 moves downward, it gradually disengages from the restraint of wedge block 23. During this process, spring 27 gradually releases the elastic force stored during compression, pushing the moving block 19 to slide inward along the inner wall of the transverse slide 20. The clamping plates 10 move synchronously. When one end of wedge block 23 moves and abuts against one side of the resisting plate 25, the two clamping plates 10 are just close to the calibration position. At this time, the oil drum is centered under the symmetrical push of the two clamping plates 10. As the wedge block 24 continues to move downward, the oil drum is centered. As the filling head continues to descend, wedge block 23 remains in abutting position against the resisting plate 25, ensuring that clamping plate 10 maintains a stable alignment throughout the process of the oil inlet pipe 5 gradually inserting into the inner wall of the barrel opening. This ensures the centering accuracy between the filling head and the barrel opening. Utilizing the limiting effect of the resisting plate 25, clamping plate 10 maintains a constant position after completing the centering positioning, preventing excessive clamping due to the continued descent of wedge block 24. This effectively avoids the problem of compression deformation of the thin-walled oil barrel caused by excessive clamping force. When the filling operation is completed and the oil box 4 and oil inlet pipe 5 rise and reset as a whole, the inclined surface of wedge block 24 gradually abuts against and pushes wedge block 23 to slide to both sides. During this process, spring 27 is gradually compressed and stores elastic force. Moving block 19 drives clamping plate 10 to move outward synchronously, causing the clamping plates 10 on both sides to move away from each other and release the clamping positioning of the oil barrel. The oil barrel continues to be conveyed forward by conveyor 1 to the next station.

[0036] like Figures 7 to 10As shown, the alignment component includes two dual-axis bearing seats 28, which are fixedly connected to one side of the clamping plate 10. Fork plate 1 29 is fixedly connected to the outer wall of the two shafts of one dual-axis bearing seat 28, and fork plate 20 is fixedly connected to the outer wall of the two shafts of the other dual-axis bearing seat 28. A convergence component is provided on one side of the clamping plate 10 to drive the shafts of the dual-axis bearing seat 28 to rotate.

[0037] During operation: In the initial state, the two fork plates 29 and 30 are parallel to the clamping plate 10, meaning they are both located on one side of the clamping plate 10, thus not affecting the normal forward transport of the oil drum on the conveyor 1. When the two clamping plates 10 move closer to each other under the drive of the moving component to center the oil drum, the converging component moves synchronously, causing the two shafts of the double-shaft bearing seat 28 to rotate simultaneously. This causes both fork plates 29 and 30 to rotate around the shafts of the double-shaft bearing seat 28. The two fork plates 29 and 30 converge towards the center from both sides simultaneously, eventually intersecting to form a surrounding limiting structure for the oil drum opening. During this process, the inner walls of the fork plates 29 and 30 abut against the outer wall of the oil drum, pushing the oil drum to a precise position aligned with the axis of the oil inlet pipe 5 outlet. This eliminates the longitudinal position deviation of the oil drum caused by the inertia of the conveyor belt starting and stopping, achieving precise positioning of the drum opening in the front-back direction. This ensures that the oil inlet pipe 5 can be accurately inserted into the drum opening for filling operations, effectively avoiding the problems of pipe collision or oil splashing during filling caused by longitudinal displacement of the drum opening.

[0038] like Figures 7 to 10 As shown, each of the gathering components includes multiple eccentric parts 31, which are respectively fixedly connected to the outer walls of both ends of the shaft of the dual-shaft bearing seat 28. Each of the outer walls of the eccentric parts 31 is fixedly connected to a connecting rope 32.

[0039] During operation: In the initial state, the eccentric heads of the multiple eccentric components 31 are positioned away from the two sets of fork plates, the connecting rope 32 is kept taut, and fork plate 1 29 and fork plate 2 30 remain parallel to the clamping plate 10; when the two clamping plates 10 move closer to each other under the drive of the moving component, the clamping plate 10 and the connected dual-axis bearing seat 28 and eccentric components 31 move inward synchronously with the moving block 19, one end of the connecting rope 32 is fixed to the outer wall of the eccentric component 31, and the clamping plate 10 moves inward. When the connecting rope 32 is subjected to external tension, the tension is transmitted to the eccentric member 31, causing the eccentric member 31 to rotate around the shaft of the double-shaft bearing seat 28 connected to it. The two shafts of the double-shaft bearing seat 28 rotate synchronously, thereby causing the first fork plate 29 and the second fork plate 30 to rotate around the shaft. The first fork plate 29 and the second fork plate 30 converge towards the center from both sides at the same time, and finally cross each other to form a surrounding limiting structure for the mouth of the oil drum, thus completing the longitudinal precise positioning of the mouth of the drum.

[0040] like Figures 7 to 10 As shown, fixed seats 34 are fixedly connected to both sides of the transverse slide 20, and rope loops 33 are fixedly connected to the top of each fixed seat 34. The end of the connecting rope 32 away from the eccentric member 31 is sleeved on the outer wall of the rope loop 33.

[0041] During operation: In the initial state, the rope loop 33 is fixed above the fixed seats 34 on both sides of the transverse slide 20 and remains stationary. The end of the connecting rope 32 away from the eccentric member 31 is sleeved on the outer wall of the rope loop 33 and kept taut. When the two clamping plates 10 move closer to each other under the drive of the moving component, the clamping plates 10 move inward, and the eccentric member 31 moves closer to the rope loop 33 along with the clamping plates 10. Since the rope loop 33 is fixed and remains stationary, the connecting rope 32 bends at the rope loop 33 and generates tension. This tension is transmitted to the eccentric member 31 through the connecting rope 32, driving the eccentric member 31 to rotate. At the same time as the eccentric member 31 rotates, the fork plate 29 and the fork plate 30 converge from both sides to the center simultaneously through the shaft, and finally cross each other to form a surrounding limiting structure for the mouth of the oil drum.

[0042] like Figures 7 to 8 As shown, a torsion spring 35 is fixedly connected to one side of both the first fork plate 29 and the second fork plate 30. The end of the torsion spring 35 away from the first fork plate 29 and the second fork plate 30 is fixedly connected to the outer wall of the dual-axis bearing seat 28.

[0043] During operation: Under the tension of the connecting rope 32, fork plate 29 and fork plate 30 rotate around the shaft of the double-axis bearing seat 28 and converge toward the center. The rotation of fork plate 29 and fork plate 30 will drive the torsion spring 35 to twist and accumulate elastic potential energy. When filling is completed and the lifting block 6 rises and resets, it drives the clamping plate 10 to move outward and return to the initial position. The connecting rope 32 gradually relaxes and loses its tension on the eccentric part 31. At this time, the elastic potential energy stored in the torsion spring 35 is quickly released, driving fork plate 29 and fork plate 30 to rotate in opposite directions around the shaft of the double-axis bearing seat 28. At the same time, it drives the eccentric part 31 to rotate in opposite directions and reset. The shaft of the double-axis bearing seat 28 rotates in opposite directions synchronously. Fork plate 29 and fork plate 30 then rotate and return to the initial state parallel to the clamping plate 10, releasing the restriction on the barrel opening.
