Description

Technical Field

[0001] This utility model relates to the technical field of filling equipment, and in particular to a dual-station filling and sealing machine. Background Technology

[0002] In modern industrial production, filling and sealing machines are widely used to fill pastes or liquids into plastic tubes and to seal and trim excess material at the end using a rotating disc, achieving efficient packaging of daily necessities. However, existing filling and sealing machines still face several significant technical challenges in practical applications. First, for pastes with a certain viscosity, existing equipment often struggles to achieve stable filling, and insufficient pressure can lead to uneven filling or low efficiency. Second, existing filling machines are typically single-station designs, unable to meet the high-efficiency production requirements of dual-station, one-to-two output, thus limiting further improvements in production efficiency. Furthermore, traditional equipment exhibits low automation in the feeding, alignment, heating, shaping, and trimming of excess material in plastic tubes, resulting in complex operation and insufficient precision, impacting overall processing quality and efficiency.

[0003] Specifically, existing filling mechanisms lack efficient switching and control mechanisms during paste extraction and delivery, resulting in an unstable filling process and difficulty in adapting to the filling requirements of high-viscosity materials. Furthermore, ensuring uniform orientation, even heating, and secure tail-end shaping of the plastic tubing in multi-station collaborative operations remains a challenge that has not been fully resolved in current technology. Additionally, the design of the waste material trimming stage is inadequate; handling the trimmed waste is inconvenient and can easily lead to equipment contamination or affect subsequent processing. Therefore, developing a filling and sealing machine capable of stable dual-station filling, possessing efficient control capabilities, and integrating multiple functional modules has become an urgent need in the industry. This invention addresses these technical problems by proposing an innovative dual-station filling and sealing machine to overcome the shortcomings of existing technologies and improve overall production efficiency and processing quality. Utility Model Content

[0004] The purpose of this invention is to provide a dual-station filling and sealing machine to overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-station filling and sealing machine is provided to solve the technical problems of low filling efficiency, inability to achieve dual-station two-outlet function, and insufficient filling stability in existing technologies for pastes. To this end, this utility model provides a dual-station filling and sealing machine, including a base, a dual-station internally heated filling head, a filling mechanism, a rotary table, and a multi-station processing system, wherein:

[0007] The filling mechanism is fixedly mounted on a machine base and includes a fixed frame, an extrusion tube, a switching valve, a material hopper, a power base, guide columns, a lead screw, a motor, and an assembly of driving and driven wheels. The fixed frame is fixedly mounted on the top of the machine base, and the extrusion tube is vertically positioned at the center of the fixed frame, with its top connected to the switching valve. The switching valve contains a valve core, which is driven by a switching cylinder to control the connection between the extrusion tube and the material hopper or outlet. The material hopper is fixedly mounted on top of the switching valve and is used to store the paste to be filled. The power base is fixedly mounted on the bottom of the machine base and has two parallel guide columns. A stabilizing push-pull plate is slidably mounted on the guide columns. The lead screw passes through the stabilizing push-pull plate and is threadedly connected to it. One end of the lead screw passes through the power base and is connected to the driving wheel via the driven wheel. The driving wheel is driven by a motor, which transmits power to the driven wheel via a belt drive, thereby rotating the lead screw. A piston rod is slidably installed inside the extrusion tube. The bottom end of the piston rod is fixedly connected to a stabilizing push-pull plate. The rotation of the screw drives the stabilizing push-pull plate to move up and down along the guide post, thereby driving the piston rod to reciprocate inside the extrusion tube.

[0008] Specifically, the working principle of the filling mechanism is as follows: S1, the motor drives the lead screw to rotate, which drives the stabilizing push-pull plate to move downward along the guide column, thereby causing the piston rod to move downward and creating a negative pressure in the extrusion tube, so that the paste is sucked from the material bucket into the extrusion tube; S2, the switching cylinder drives the valve core in the rotary valve to rotate, so that the extrusion tube is connected to the discharge port; S3, the motor drives the lead screw to rotate again, which drives the stabilizing push-pull plate to move upward along the guide column, thereby causing the piston rod to move upward and smoothly push the paste from the discharge port to the feed port of the heating filling head in the dual-station system.

[0009] Furthermore, the dual-station internal heating filling head includes a guide plate, a lifting frame, an injection pipe, a filling cylinder, and a feed inlet. The guide plate is fixedly installed on the top of the machine base, and the lifting frame is slidably mounted on the guide plate and driven to move up and down by the lifting cylinder. The injection pipe is fixedly installed on the lifting frame, and a filling cylinder is provided at the top of the injection pipe. A sealing plug is provided at the output end of the filling cylinder, and the sealing plug is arranged inside the injection pipe to control the opening and closing of the injection pipe. The filling cylinder drives the sealing plug to move up and down to realize the filling and stopping of the paste. A feed inlet is opened on the side wall of the injection pipe, and the feed inlet is connected to the discharge port of the filling mechanism through a pipe.

[0010] Furthermore, the working principle of the dual-station internal heating filling head is as follows: S1, the lifting cylinder drives the lifting frame to move downward along the guide plate, bringing the injection tube closer to the plastic tubing; S2, the filling cylinder retracts the sealing plug upward in preparation for filling; S3, the paste enters the injection tube through the feed inlet; S4, after filling, the heating function integrated into the dual-station internal heating filling head heats the paste and simultaneously completes the sealing operation. Through the above steps, the dual-station internal heating filling head achieves simultaneous processing of two plastic tubings, significantly improving production efficiency.

[0011] Specifically, the rotary table and multi-station processing system includes a base, a rotary table, placement seats, and multiple processing stations. The base is fixedly mounted on the equipment's foundation, and the rotary table is rotatably mounted on the base. Multiple placement seats are arranged in a ring on the rotary table, each seat supporting a plastic tube. The rotary table is arranged sequentially according to the processing order as follows: a feeding mechanism, a alignment mechanism, a filling mechanism, a heating mechanism, a clamping and shaping mechanism, a waste material cutting mechanism, and a discharge mechanism. The feeding mechanism places the plastic tube onto the placement seats. The alignment mechanism uses a photoelectric detector and a servo motor to control the alignment rotating wheel, ensuring the plastic tube's orientation is consistent. The filling mechanism completes the filling of the paste. The heating mechanism heats the tail of the plastic tube using a hot air nozzle. The clamping and shaping mechanism clamps, holds, and shapes the heated tail using a tail clamp and a clamping and shaping block. The waste material cutting mechanism cuts off excess waste material using a cutting blade. Finally, the discharge mechanism ejects the processed product.

[0012] Furthermore, the feeding mechanism includes a storage tank, a first crank-slider assembly, a second crank-slider assembly, a support block, a traction motor, and a clamp. The storage tank is fixedly installed on the top of the machine base. The bottom of the storage tank is equipped with the first crank-slider assembly, which controls the descent of the plastic hose. The discharge end of the storage tank is equipped with the second crank-slider assembly and the support block. The support block has double grooves for simultaneously accommodating two plastic hoses. A liftable baffle is provided above the support block, controlled by a lifting mechanism, to block unused plastic hoses. The traction motor is fixedly installed on the discharge end of the storage tank. The output end of the traction motor is equipped with a first crank-rocker assembly. One end of the first crank-rocker assembly controls the swinging rocker arm. A positioning seat is hinged to the bottom of the rocker arm, and a servo motor is fixedly installed inside the positioning seat. A clamp is hinged to the top of the rocker arm. The clamp is connected to the servo motor through a belt drive assembly. The servo motor drives the clamp to swing relative to the rocker arm through the belt drive assembly, thereby clamping and transporting the plastic hose on the support block to the placement seat.

[0013] Specifically, the alignment mechanism includes a photoelectric detector, a horizontal feeding assembly, an alignment rotating wheel, and a pressure block. The photoelectric detector is fixedly mounted on the top of the frame and is used to identify labels on the plastic hose. The horizontal feeding assembly is mounted on the frame and is used to control the horizontal movement of the alignment rotating wheel. A servo motor is installed on the horizontal feeding assembly, which drives the alignment rotating wheel to rotate and adjust the direction of the plastic hose. A second lifting cylinder is also provided on the base, and a pressure block is installed at the output end of the second lifting cylinder. The pressure block presses down on the plastic hose through lifting and lowering movement, ensuring that the plastic hose remains stable during the alignment process.

[0014] Furthermore, the heating mechanism includes a first lifting cylinder, a hot air head, and a heating control assembly. The first lifting cylinder is fixedly mounted on the base, and the hot air head is driven to move up and down by the first lifting cylinder. When the rotating disc moves the plastic hose below the heating mechanism, the first lifting cylinder drives the hot air head to move downward, heating the tail end of the plastic hose until it reaches a molten state.

[0015] Specifically, the clamping and shaping mechanism includes an impression cylinder, a tail clamp, and clamping and shaping blocks. The impression cylinder is fixedly mounted on the machine base, and the tail clamp is driven by the impression cylinder. Two pairs of clamping and shaping blocks are fixedly provided at the clamping opening of the tail clamp, and the side walls of the clamping and shaping blocks are provided with paired textures for clamping, biting, and shaping the tail of the hot-melted plastic hose.

[0016] Furthermore, the scrap material cutting mechanism includes a cutting positioning frame, opposing cylinders, and cutting heads. The cutting positioning frame is fixedly mounted on the machine base, and two sets of opposing cylinders are provided on the cutting positioning frame. A cutting head is fixedly installed at the end of the piston rod of each set of opposing cylinders. The cutting heads are arranged in a vertically rotating manner and are used to cut the tail end of the plastic tube. An inclined scrap material discharge plate is provided on one side of the bottom of the cutting positioning frame, and the cut scrap material slides down through the scrap material discharge plate.

[0017] Specifically, the unloading mechanism includes a curved baffle and a blanking plate. The curved baffle is mounted above the rotary table, and the blanking plate is inclined and fixedly installed on the machine base. When the rotary table moves the processed plastic hose to the curved baffle, the curved baffle abuts against the plastic hose and gradually squeezes the plastic hose as the rotary table rotates, eventually pushing the plastic hose down and sliding it out of the blanking plate, thus completing the unloading process.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The above technical solutions achieve efficient operation of the dual-station filling and sealing machine. The filling mechanism controls the suction and pushing process of the paste through a switching valve, ensuring stable paste transfer and suitable for filling high-viscosity pastes. The dual-station internal heating filling head drives the lifting frame through a lifting cylinder, cooperating with the filling cylinder to achieve precise paste filling. The rotary table and multi-station processing system ensures the uniformity of plastic tubing orientation and processing accuracy through precision control components such as photoelectric detectors and servo motors. The feeding mechanism, through the design of the support block and clamps, enables simultaneous feeding at both stations. The alignment mechanism, through the cooperation of photoelectric detectors and servo motors, ensures the consistency of plastic tubing orientation. The heating mechanism heats the tail of the plastic tubing with a hot air head, providing the foundation for subsequent clamping and shaping. The clamping and shaping mechanism, through the design of the clamping and shaping block, achieves efficient shaping of the tail. The excess material cutting mechanism, through the design of the cutting blade, achieves precise cutting of the excess material at the tail. The unloading mechanism, through the cooperation of curved baffles and dropping plates, achieves automatic unloading of processed products.

[0020] In summary, this utility model significantly improves production efficiency and product quality by optimizing the structural design of the filling mechanism, the dual-station internal heating filling head, the rotary disk, and the multi-station processing system. It is suitable for the packaging needs of various pastes or liquids in the daily necessities industry. Attached Figure Description

[0037] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0038] A dual-station filling and sealing machine, combined with an auxiliary... Figure 1 To be continued Figure 11 The specific implementation method is described in detail. In this embodiment, the equipment includes a base, a dual-station internal heating filling head 1, a filling mechanism 2, a rotary table 40, and a multi-station processing system. The structure and function of each part are explained through specific operating principles and processes.

[0039] The filling mechanism 2 is fixedly mounted on the machine base and mainly consists of a fixed frame 18, an extrusion pipe 11, a switching valve 20, a material hopper 19, a power base, guide columns 15, a lead screw 14, a motor 8, a drive wheel 16, and a driven wheel 17. The fixed frame 18 is fixedly mounted on the top of the machine base. The extrusion pipe 11 is vertically positioned at the center of the fixed frame 18, and its top is connected to the switching valve 20. The switching valve 20 contains a valve core 21, which is driven by a switching cylinder 10 to switch the connection between the extrusion pipe 11 and the material hopper 19 or the outlet 9. The material hopper 19 is fixed to the top of the switching valve 20 and is used to store the paste to be filled. The power base is fixed to the bottom of the machine base and has two parallel guide columns 15 on it. A stabilizing push-pull plate 13 is slidably mounted on the guide columns 15. The lead screw 14 passes through the stabilizing push-pull plate 13 and is threadedly connected to it. One end of the lead screw 14 passes through the power base and is connected to the drive wheel 16 via the driven wheel 17. The motor 8 is fixed to one side of the power base and transmits power to the driven wheel 17 via belt drive, thereby driving the lead screw 14 to rotate. A piston rod 12 is slidably installed inside the extrusion tube 11, with its bottom end fixedly connected to the stabilizing push-pull plate 13. When the motor 8 starts, the driving wheel 16 drives the driven wheel 17 to rotate via belt drive, which in turn causes the lead screw 14 to rotate, pushing the stabilizing push-pull plate 13 up and down along the guide post 15, ultimately causing the piston rod 12 to reciprocate within the extrusion tube 11. In S1, the switching cylinder 10 drives the valve core 21 to push forward, at which point the material bucket 19 is connected to the extrusion tube 11, and the piston rod 12 moves downward to draw up the paste. In S2, the switching cylinder 10 drives the valve core 21 to retract backward, connecting the extrusion tube 11 to the discharge port 9. Subsequently, the motor 8 controls the piston rod 12 to move upward, smoothly pushing the paste to the discharge port 9.

[0040] The working principle of the filling mechanism 2 is as follows: S1, the motor 8 drives the lead screw 14 to rotate, which drives the stabilizing push-pull plate 13 to move downward along the guide post 15, thereby causing the piston rod 12 to move downward, forming a negative pressure in the extrusion tube 11, and the paste is sucked into the extrusion tube 11 from the material tank 19; S2, the switching cylinder 10 drives the valve core 2121 in the rotary valve 20 to push forward, at which time the material tank 19 is connected to the extrusion tube 11, and the piston rod 12 moves downward to draw and collect a part of the paste; then the switching cylinder 10 drives the valve core 2121 in the rotary valve 20 to retract backward, so that the extrusion tube 11 is connected to the discharge port 9; S3, the motor 8 drives the lead screw 14 to rotate again, which drives the stabilizing push-pull plate 13 to move upward along the guide post 15, thereby causing the piston rod 12 to move upward, and smoothly push the paste out from the discharge port 9 to the feed port 4 of the dual-station heating filling head 1.

[0041] The dual-station internal heating filling head 1 includes a guide plate 6, a lifting frame 5, an injection pipe, a filling cylinder 3, and a feed inlet 4. The guide plate 6 is fixedly installed on the top of the machine base. The lifting frame 5 is slidably mounted on the guide plate 6 and is driven to move up and down by the lifting cylinder 7. The injection pipe is fixed on the lifting frame 5, and the top is equipped with the filling cylinder 3. The output end of the filling cylinder 3 is equipped with a sealing plug, which is arranged inside the injection pipe to control the opening and closing of the injection pipe. The filling cylinder 3 drives the sealing plug to move up and down to realize the filling and stopping of the paste. The side wall of the injection pipe has a feed inlet 4, which is connected to the discharge port 9 of the filling mechanism 2 through a pipe. When the lifting cylinder 7 drives the lifting frame 5 to move downward, the injection pipe approaches the plastic hose, and the filling cylinder 3 drives the sealing plug to retract upward, and the paste enters the plastic hose through the injection pipe to complete the filling.

[0042] The working principle of the dual-station internal heating filling head 1 is as follows: S1, the lifting cylinder 7 drives the lifting frame 5 to move downward along the guide plate 6, bringing the injection pipe closer to the plastic tubing; S2, the filling cylinder 3 retracts the sealing plug upward in preparation for filling; S3, the paste enters the injection pipe through the feed port 4; S4, after filling is completed, the integrated heating function of the dual-station internal heating filling head 1 heats the paste and simultaneously completes the sealing operation. Through the above steps, the dual-station internal heating filling head 1 achieves simultaneous processing of two plastic tubings, significantly improving production efficiency.

[0043] In actual operation, the overall workflow of the dual-station internal heating filling head 1 and filling mechanism 2 is as follows: First, the operator pours the paste to be filled into the material tank 19, and then starts the equipment. The motor 8 in the filling mechanism 2 drives the lead screw 14 to rotate, which drives the stabilizing push-pull plate 13 to move downward along the guide column 15, thereby causing the piston rod 12 to move downward, forming a negative pressure in the extrusion tube 11, and the paste is sucked from the material tank 19 into the extrusion tube 11. Next, the switching cylinder 10 drives the valve core 21 in the rotary valve 20 to push forward. At this time, the material barrel 19 is connected to the extrusion pipe 11, and the piston rod 12 moves downward to draw and collect a portion of the paste. Then, the switching cylinder 10 drives the valve core 21 in the rotary valve 20 to retract backward, so that the extrusion pipe 11 is connected to the discharge port 9. Subsequently, the motor 8 drives the lead screw 14 to rotate again, driving the stabilizing push-pull plate 13 to move upward along the guide post 15, thereby causing the piston rod 12 to move upward and smoothly push the paste from the discharge port 9 to the inlet 4 of the dual-station heating filling head 1. At the same time, the lifting cylinder 7 in the dual-station heating filling head 1 drives the lifting frame 5 to move downward along the guide plate 6, so that the injection pipe is close to the plastic hose. The filling cylinder 3 retracts the sealing plug upward in preparation for filling, and the paste enters the injection pipe through the inlet 4 to complete the filling.

[0044] The rotary table 40 and multi-station processing system include a base, a rotary table 40, placement seats 54, and multiple processing stations. The base is fixedly mounted on the equipment base, and the rotary table 40 is rotatably mounted on the base. Multiple placement seats 54 are arranged in a ring on the rotary table 40, each placement seat 54 for supporting plastic tubing. The rotary table 40 is arranged in the following order according to the processing sequence: a feeding mechanism 22, a alignment mechanism 23, a filling mechanism 2, a heating mechanism 25, a clamping and shaping mechanism 26, a waste material cutting mechanism 27, and a discharge mechanism 28. The feeding mechanism 22 is responsible for placing the plastic tube onto the placement seat 54. The alignment mechanism 23 controls the alignment rotating wheel 56 through the photoelectric detector 55 and the servo motor 58 to unify the direction of the plastic tube. The filling mechanism 2 completes the filling of the paste. The heating mechanism 25 heats the tail of the plastic tube through the hot air head 43. The clamping and shaping mechanism 26 clamps, bites and shapes the heated tail through the tail clamp 46 and the clamping and shaping block 47. The excess material cutting mechanism 27 cuts off the excess material through the cutting blade head 49. Finally, the unloading mechanism 28 pushes out the processed product.

[0045] The feeding mechanism 22 includes a storage tank, a first crank-slider assembly 29, a second crank-slider assembly 30, a support block 32, a traction motor 37, and a clamp 33. The storage tank is fixedly installed on the top of the machine base, and the first crank-slider assembly 29 is located at the bottom to control the descent of the plastic hose. The discharge end of the storage tank is equipped with the second crank-slider assembly 30 and the support block 32. The support block 32 has double slots to accommodate two plastic hoses simultaneously. A liftable baffle 31 is located above the support block 32. The baffle 31 is controlled by a lifting mechanism to block unused plastic hoses. The traction motor 37 is fixedly installed at the discharge end of the storage tank, and its output end is equipped with a first crank-rocker assembly 38. One end of the first crank-rocker assembly 38 controls the swinging rocker arm 35. The bottom of the rocker arm 35 is hinged to a positioning seat, and a servo motor 58 is fixedly installed inside the positioning seat. The top of the rocker arm 35 is hinged to the clamp 33, which is connected to the servo motor 58 via the belt drive assembly 34. The servo motor 58 drives the clamp 33 to swing relative to the rocker arm 35 via the belt drive assembly 34, thereby clamping and transporting the plastic hose on the support block 32 to the placement seat 54.

[0046] The alignment mechanism 23 includes a photoelectric detector 55, a horizontal feeding assembly 57, an alignment rotating wheel 56, and a pressure block 53. The photoelectric detector 55 is fixedly mounted on the top of the frame and is used to identify labels on the plastic hose. The horizontal feeding assembly 57 is mounted on the frame and is used to control the horizontal movement of the alignment rotating wheel 56. A servo motor 58 is installed on the horizontal feeding assembly 57, which drives the alignment rotating wheel 56 to rotate and adjust the direction of the plastic hose. A second lifting cylinder 52 is also provided on the base, and a pressure block 53 is installed at the output end of the second lifting cylinder 52. The pressure block 53 presses down on the plastic hose through lifting and lowering movement, ensuring the plastic hose remains stable during the alignment process.

[0047] The heating mechanism 25 includes a first lifting cylinder 44, a hot air head 43, and a heating control assembly. The first lifting cylinder 44 is fixedly mounted on the base, and the hot air head 43 is driven to move up and down by the first lifting cylinder 44. When the rotating disk 40 moves the plastic hose below the heating mechanism 25, the first lifting cylinder 44 drives the hot air head 43 to move downward, heating the tail end of the plastic hose until it reaches a molten state.

[0048] The clamping and shaping mechanism 26 includes an impression cylinder 45, a tail clamp 46, and clamping and shaping blocks 47. The impression cylinder 45 is fixedly mounted on the machine base, and the tail clamp 46 is driven by the impression cylinder 45. Two pairs of clamping and shaping blocks 47 are fixedly installed at the clamping opening of the tail clamp 46. The side walls of the clamping and shaping blocks 47 are provided with paired textures for clamping, biting, and shaping the tail of the hot-melted plastic hose.

[0049] The scrap cutting mechanism 27 includes a cutting positioning frame 50, opposing cylinders 48, and cutting heads 49. The cutting positioning frame 50 is fixedly mounted on the machine base. Two sets of opposing cylinders 48 are provided on the cutting positioning frame 50, and a cutting head 49 is fixedly mounted at the end of the piston rod of each set of opposing cylinders 48. The cutting heads 49 are arranged in a vertically rotating manner and are used to cut the tail end of plastic hoses. An inclined scrap discharge plate 51 is provided on one side of the bottom of the cutting positioning frame 50, through which the cut scrap slides down.

[0050] The unloading mechanism 28 includes a curved baffle 39 and a discharge plate 41. The curved baffle 39 is mounted above the rotary table 40, and the discharge plate 41 is inclined and fixedly installed on the machine base. When the rotary table 40 moves the processed plastic hose to the curved baffle 39, the curved baffle 39 abuts against the plastic hose and gradually squeezes the plastic hose as the rotary table 40 rotates, eventually pushing the plastic hose down and sliding it out of the discharge plate 41, completing the unloading process.

[0051] In this embodiment, during equipment operation, the feeding mechanism 22 first places the plastic tubing onto the placement seat 54, and then the rotating disk 40 sequentially feeds the plastic tubing into each processing station. The alignment mechanism 23 identifies the label on the plastic tubing using a photoelectric detector 55 and adjusts the direction of the plastic tubing using a servo motor 58 to ensure consistency. The filling mechanism 2 controls the suction and pushing process of the paste using a switching valve 20 to ensure smooth transfer and accurate filling of the paste into the plastic tubing. The heating mechanism 25 heats the tail of the plastic tubing using a hot air head 43 to bring it to a hot-melt state, providing conditions for subsequent clamping and shaping. The clamping and shaping mechanism 26 clamps, bites, and shapes the heated tail using a clamping and shaping block 47 to form a closed structure. The excess material cutting mechanism 27 precisely cuts off the excess material using a cutting blade 49 to ensure a neat product appearance. Finally, the unloading mechanism 28 automatically pushes out the processed plastic tubing through the cooperation of the curved baffle 39 and the dropping plate 41, completing the entire processing flow.

[0052] This utility model significantly improves production efficiency and product quality by optimizing the structural design of the filling mechanism 2, the dual-station internal heating filling head 1, the rotary disk 40, and the multi-station processing system. It is suitable for the packaging needs of various pastes or liquids in the daily necessities industry.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
