Description

Technical Field

[0001] The invention relates to the technical field of water emulsion filling, in particular to a liquid filling device of a water emulsion double filling machine. Background Art

[0002] The turntable filling device is a highly efficient equipment for automatic filling of liquid products. It is widely used in the production of cosmetics such as lotions and essences. Its main function is to improve production efficiency and ensure filling accuracy and consistency. Through automated operation, this equipment reduces manual intervention and production costs, and can accurately control the filling volume of each bottle of product, thereby avoiding liquid waste and uneven filling. The core component of this type of filling device is the turntable, which is driven by a motor to rotate. The empty bottle is sent to the bottle seat on the turntable and positioned. As the turntable rotates, the bottle goes through each filling and sealing process in turn. The filling system consists of a liquid storage tank, a pipeline and a precise filling head. The liquid is transported to the filling head through the pipeline. The liquid flow rate is adjusted by controlling the valve to ensure that the liquid filling amount of each bottle is accurate and consistent. The bottle moves continuously on the turntable and is finally processed by the capping or sealing system; such as the multi-station water emulsion filling and capping machine disclosed by the authorization announcement number CN214059865U, including a machine, a turntable rotatably arranged on the machine, and a filling device and a capping device arranged around the turntable. The turntable is provided with a plurality of jigs around its circumference. The jigs include a first mounting seat, a threaded rod and two clamping blocks. The first mounting seat is arranged on the turntable. Both ends of the threaded rod are rotatably connected to the first mounting seat and arranged along the radial direction of the turntable. The end of the threaded rod away from the center of the turntable protrudes from the side of the first mounting seat to form a turntable. The threaded rod has two threaded sections with opposite threads. The method of arranging a plurality of jigs on the turntable to circulate and transport the bottle body is conducive to reducing the space occupied by the entire equipment, thereby facilitating transportation. At the same time, by adjusting the distance between the two clamps through the threaded rod, bottles of different sizes can be fixed, which is beneficial to improve the versatility of the equipment. However, during the use of the above technical solution, the conveyor belt used to transport the bottle body and the turntable machine for changing the bottle body position are driven by two motors. Therefore, in order to ensure the synchronous bottle body transportation and bottle body position change of the filling machine, the two motors need to start and stop synchronously. In this process, the operation of the two motors is usually coordinated by a PLC control system. However, since the control accuracy and response speed of the motor itself will be affected by factors such as load changes, mechanical friction, and temperature changes, the synchronization between the motors will gradually deviate. When the filling device runs for a long time, the thermal expansion effect of the motor will cause a slight change in the motor speed, or the load fluctuation of the motor will affect the output torque of the motor, thereby affecting the accuracy of the synchronous control. This accuracy error will directly affect the conveying speed of the bottle body and the rotation speed of the turntable, causing the bottle body to be misaligned during transportation and positioning.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1, by Figures 1 to 4 The present invention comprises a base 1, a conveying frame 2 fixed on the top of the base 1, and a gear-type turntable bottle-separating structure 6 installed on the top of the base 1 and located above the conveying frame 2.

[0019] Embodiment 2, based on embodiment 1, Figure 2 , Figure 4 , Figure 5 and Figure 6 It is given that the belt transmission structure 5 includes a main shaft roller, a secondary shaft roller and a conveyor belt wound around the outer circumference of the main shaft roller and the secondary shaft roller, which are rotatably installed at both ends of the conveyor frame 2. The belt transmission structure 5 also includes rollers rotatably installed inside the conveyor frame 2 at equal intervals. The outer surface of the roller is in contact with the inner wall surface of the conveyor belt. One end of the secondary shaft roller is fixedly connected to the output end of the stepper motor 15 through a coupling. The PLC control panel 7 accurately controls the start, stop, running speed and working state of each stepper motor 15 according to the preset program and control logic. The rotary power of the stepper motor 15 is first transmitted to the belt transmission structure 5, and the bottle to be filled is horizontally moved by the belt transmission structure 5. The gear-type rotating disc bottle-distributing structure 6 comprises a pillow block 3 fixed to the top of the base 1 through a guide column, a rotating shaft 601 rotatably mounted inside the pillow block 3, a transmission shaft 603, and a bottle-distributing disc 602 fixed to the top of the rotating shaft 601. Six semicircular notches with equal spacing are arranged on the arc surface outer wall of the bottle-distributing disc 602, and the semicircular notches are used for bottles to enter the bottle-distributing disc 602. The bevel gear reversing synchronous transmission mechanism 14 includes a longitudinal shaft 1401 rotatably mounted on the outer wall of one side of the conveying frame 2, a synchronous wheel transmission structure 1404 for connecting the longitudinal shaft 1401 and the secondary shaft roller, a driving shaft 1402 rotatably mounted on one side of the bottom end of the pillow block 3, and a bevel gear transmission structure 1403 for connecting the longitudinal shaft 1401 and the driving shaft 1402. A three-gear transmission structure 604 for maintaining power connection is installed between the top of the driving shaft 1402 and the transmission shaft 603 and the rotating shaft 601; The extended lines of the central axis of the longitudinal axis 1401 and the driving shaft 1402 intersect and form a vertical structure. The bevel gear transmission structure 1403 includes a driving bevel gear fixed at one end of the longitudinal axis 1401 and a driven bevel gear at the bottom end of the driving shaft 1402. The three-gear transmission structure 604 includes a final gear plate fixed at one end of the surface of the rotating shaft 601, and a secondary gear and a primary gear fixed at the transmission shaft 603 and the top of the driving shaft 1402. The primary gear, the secondary gear, and the final gear plate are meshed in sequence. The diameters of the primary gear and the secondary gear are the same. A part of the rotary power of the belt transmission structure 5 is transmitted through the synchronous wheel transmission structure 1 404 is transmitted to the longitudinal shaft 1401, and the longitudinal shaft 1401 and the bevel gear transmission structure 1403 drive the driving shaft 1402 to rotate. When the stepping motor 15 drives the belt transmission structure 5 to transmit the bottle body in the horizontal positive direction of the X axis, the rotation power of the longitudinal shaft 1401 is transmitted to the rotating shaft 601 through the bevel gear transmission structure 1403, the driving shaft 1402, the transmission shaft 603, and the three-gear transmission structure 604 in sequence, and then the rotating shaft 601 and the bottle separation plate 602 will rotate clockwise and send the bottle body to the single-cylinder bottle cap releasing module 12 and the capping device 13, thereby completing the workpiece conversion and movement of the bottle body; Using a stepper motor 15 and completing power transmission through a bevel gear reversing synchronous transmission mechanism 14 can significantly reduce the installation space required for the main shaft, making the production line more compact. At the same time, when the belt transmission structure 5 and the gear-type turntable bottle separation structure 6 are controlled by the same motor, the PLC control panel 7 only needs to adjust the parameters of one motor to synchronously control the start, stop and operation status of the two systems. This not only reduces the control complexity, but also can more accurately control the synchronization between the two structures, ensure the smooth flow of the bottle body, and avoid the occurrence of production line stagnation and bottle body dislocation.

[0020] Embodiment 3, based on embodiment 2, Figure 6 and Figure 7 It is given that the cage 11 includes a plurality of steel columns 1101 fixed on the outer wall of one side of the Z-shaped bending frame 10, and the steel columns 1101 are inclined upward from one end close to the Z-shaped bending frame 10 to the other end, and the plurality of steel columns 1101 surround a rectangular cavity channel, and at least two circular hoops 1102 are welded at one end of the surface of the plurality of steel columns 1101. The staff places a plurality of bottle caps to be used in the cavity channel surrounded by the plurality of steel columns 1101, and the circular hoops 1102 serve to tighten and fix the plurality of steel columns 1101. Since the steel columns 1101 extend obliquely upward, the bottle caps in the cavity channel naturally slide to the single-cylinder bottle cap release module 12 under the action of gravity; The single-cylinder bottle cap releasing module 12 comprises a notch plate 1201 fixed on the outer wall of the other side of the Z-shaped bending frame 10, a capping tongue 1202 and a right-angle shaft frame 1203 fixed at the bottom end of the notch plate 1201, a gap portion connected to the rectangular cavity channel is arranged between the capping tongue 1202 and the notch plate 1201, a connecting seat 1204 is rotatably installed on both sides of the top of the right-angle shaft frame 1203, a clamping claw 1205 is fixed on one end of the surface of the connecting seat 1204, and a torsion spring 1208 for preventing the clamping claw 1205 from deflecting outward is installed at the bottom end of the right-angle shaft frame 1203, and the bottle cap in the cavity channel slides between the notch plates 1201 and the notch plates 1201, at which time the elastic force of the torsion spring 1208 makes the two clamping claws 1205 always firmly clamp the bottle cap, that is, the two clamping claws 1205 always hold the bottle cap under the torsion of the elastic force of the torsion spring 1208; The cage 11 also includes a cylinder 1206 installed on one side of the top of the Z-shaped bending frame 10, and an inner folding C-mouth frame 1207 is fixed to the top of the piston rod of the cylinder 1206. The bottom end of the inner folding C-mouth frame 1207 passes through between the two claws 1205 and slides with the claws 1205; the inner folding C-mouth frame 1207 is narrow at the bottom and wide at the top, and a rectangular slide groove is provided on the outer wall of the claw 1205 on the side close to the pressure cover tongue 1202. The inner folding C-mouth frame 1207 slides with the claw 1205 through the rectangular slide groove. When the bottle dispensing plate 602 moves the bottle body to the bottom of the notch plate 1201, the PLC control panel 7 controls the cylinder 1206 After one action, the piston rod of the cylinder 1206 drives the inner-folding C-mouth frame 1207 to move downward. Since the inner-folding C-mouth frame 1207 is narrow at the bottom and wide at the top, the inner-folding C-mouth frame 1207 opens the two claws 1205 outward to release the bottle cap and let it fall on the bottle mouth after liquid injection. At this time, the torsion spring 1208 is twisted and deformed. When the inner-folding C-mouth frame 1207 is reset upward, the torsion spring 1208 also returns to its initial state, so that the connecting seat 1204 and the claws 1205 are deflected and reset and re-hold the next bottle cap. It only relies on one cylinder to complete this series of tasks, reducing the complexity of the bottle cap release and clamping process.

[0021] When the embodiment of the present application is in use, the staff first places several bottles to be filled and processed on the conveyor rack 2 at equal intervals to ensure that there is an equidistant gap between two adjacent bottles. In this process, the conveyor rack 2 is responsible for supporting and guiding the bottles to the belt conveyor structure 5. At this time, the belt conveyor structure 5 is driven by the stepper motor 15. By accurately controlling the operation of the stepper motor 15, the belt conveyor structure 5 can be ensured to operate stably, and the conveying speed and step distance can be accurately adjusted according to production requirements. When the bottle is on the belt conveyor structure 5, the photoelectric switch 401 detects the position of the bottle in real time. The photoelectric switch 401 can accurately sense the passage of the bottle based on its reflection principle, ensuring that the bottle always runs on a predetermined track to avoid the bottle. The bottles are misplaced or piled up. During this process, the signal of the photoelectric switch 401 is transmitted to the PLC control panel 7. The PLC control panel 7 monitors the entire conveying process in real time and adjusts the action of the stepper motor 15 according to the feedback of the photoelectric switch 401 to ensure the smooth conveying of the bottles. During the operation of the belt conveyor structure 5, a part of the rotary power of the stepper motor 15 is also transmitted to the gear-type turntable bottle-splitting structure 6 through the bevel gear reversing synchronous transmission mechanism 14. The gear-type turntable bottle-splitting structure 6 receives the bottles from the belt conveyor structure 5. The gear-type turntable bottle-splitting structure 6 accurately transfers the bottles from the belt conveyor structure 5 to each workstation to complete the next operation. In this stage, the bevel gear reversing synchronous transmission mechanism 14 ensures that the gear-type turntable bottle-splitting structure 6 and the belt conveyor are in a stable state. The synchronous operation of the conveying structure 5 enables the bottles to be seamlessly connected between the two structures to avoid stagnation or misalignment, and the precise control of the stepper motor 15 and the gear-type turntable bottle separation structure 6 can adjust the running speed according to the interval between the bottles and production requirements to ensure that each bottle enters the next process in a predetermined order. When the photoelectric switch 401 detects the bottle, the photoelectric switch 401 feeds back the signal to the PLC control panel 7, and the PLC control panel 7 turns off the stepper motor 15. At this time, the belt conveyor structure 5 and the gear-type turntable bottle separation structure 6 stop moving, and the electromagnetic flow valve 9 automatically adjusts the injection volume according to the volume of the bottle and the production requirements preset in the PLC control panel 7 to ensure that the filling volume of each bottle is consistent to meet the quality standards. After the bottle is filled with liquid, the stepper motor 15 continues to operate so that the gear-type turntable bottle-separating structure 6 moves the bottle that has been filled with liquid to the position of the single-cylinder bottle cap releasing module 12. At this time, the releasing step of the single-cylinder bottle cap releasing module 12 begins, which accurately releases the bottle cap from the storage position and places the bottle cap on the bottle mouth that has been filled. After the bottle cap is released, the stepper motor 15 operates again, so that the gear-type turntable bottle-separating structure 6 sends the bottle to the capping device 13. At this time, the bottle cap begins to be tightened by the capping device 13. After completing the operations of liquid filling, capping, and capping, the bottle is sent back to the other side of the belt conveyor structure 5 through the gear-type turntable bottle-separating structure 6. On the belt conveyor structure 5, the bottle is stably conveyed to the next stage.Until the entire production process is completed.
