Description

Technical Field

[0001] This utility model relates to the field of plastic sealing device technology, and in particular to a multi-stage collaborative continuous plastic sealing device. Background Technology

[0002] In modern industrial production, especially for the individual packaging of small hardware parts, electronic components, stationery, food, and other products, shrink-wrapping technology is widely used due to its advantages such as good sealing, moisture protection, display properties, and ease of transportation and storage. Continuous shrink-wrapping equipment is a key piece of equipment for achieving efficient and automated production.

[0003] Existing sealing devices typically include basic functional units such as unwinding, forming, loading, side sealing, and final sealing and cutting. However, these devices still have some significant shortcomings in practical applications. First, traditional equipment is often designed for single or specific product specifications, and its material guide channel is fixed and cannot be adjusted. When different shapes or sizes of products need to be packaged on the production line, operators must stop the machine and perform tedious disassembly, replacement, and readjustment of components such as the material guide mechanism and the forming device. Most equipment on the market still requires a long downtime and adjustment when frequently changing products, making it difficult to meet the needs of flexible production. Therefore, a multi-stage collaborative continuous sealing device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a multi-segment collaborative continuous molding device to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a multi-segment cooperative continuous sealing device, including a body, a frame, an unwinding roller, a drive motor, a drive roller, and an auxiliary roller. The frame is fixedly connected to the front of the body, and the unwinding roller is movably connected to the inner side of the frame.

[0007] A drive motor is fixedly connected to the side of the frame, and an active roller is fixedly connected to the output end of the drive motor.

[0008] An auxiliary roller is movably connected to the inner side of the frame, and the auxiliary roller is located in front of the active roller;

[0009] An oblique guide rod is fixedly connected to the inner side of the frame;

[0010] A bag guide mechanism is fixedly connected to the front of the frame, and the opening of the bag guide mechanism gradually decreases from top to bottom;

[0011] The bottom end of the bag guiding mechanism is fixedly connected to a bag guiding cylinder, which has an opening facing away from the longitudinal direction for the auxiliary channel to insert / feed materials.

[0012] A side sealing mechanism is fixedly connected to the front of the machine body, an electric cylinder is fixedly connected to the side of the side sealing mechanism, a dynamic sealing element is fixedly connected to the output end of the electric cylinder, and a static sealing element is fixedly connected to the inner side of the side sealing mechanism.

[0013] Two film-collecting rollers are movably connected to the front of the machine body, and the film-collecting rollers are driven by a motor inside the machine body;

[0014] A sealing mechanism is fixedly connected to the front of the machine body, an electric cylinder is fixedly connected to the side of the sealing mechanism, a moving sealing knife is fixedly connected to the output end of the electric cylinder, and a stationary sealing knife is fixedly connected to the inner side of the sealing mechanism.

[0015] A bracket is fixedly connected to the top of the machine body, and a ring track is fixedly connected to the top of the bracket. Several sliders are movably connected to the outer surface of the ring track. The sliders can be locked in position. A guide channel is fixedly connected to the front of the sliders. A secondary channel is movably connected to the inside of the guide channel. The secondary channel is retractable.

[0016] The side of the feed channel is threaded with a fastening pin, and the end of the fastening pin abuts against the side of the auxiliary channel.

[0017] Preferably, in any of the above embodiments, the unwinding roller is located above the drive roller, and the cross-sectional shape of the bag guiding mechanism is arc-shaped.

[0018] The drive motor starts, causing the drive roller to rotate. The packaging film on the unwind roller is conveyed by the cooperation of the drive roller and the auxiliary roller, and then guided to the bag-guiding mechanism along the inclined guide rod. The opening of the bag-guiding mechanism gradually decreases from top to bottom, guiding and initially shaping the packaging film, gradually forming it into a bag-shaped structure suitable for inserting small parts.

[0019] Small parts bagging: Select the appropriate feed channel according to different product requirements. The feed channel is connected to different material sources through the flange at the top. Small parts enter the feed channel from the material source, and then accurately enter the bag-shaped structure formed inside the bag guiding mechanism through the retractable secondary channel to complete the bagging operation.

[0020] Side sealing: The packaging bag containing small parts enters the side sealing mechanism. The electric cylinder pushes the moving sealing element to move towards the stationary sealing element. The electric heating mechanism on the end face of the moving sealing element heats up, so that when the moving sealing element and the stationary sealing element come into contact, the side of the packaging bag is heat-sealed, completing the side sealing process.

[0021] After the side sealing process, two film-collecting rollers, movably connected to the front of the machine body, are driven by an internal motor to press together any excess edges of the packaging film. The side-sealed packaging bag then enters the sealing mechanism. An electric cylinder on the side of the sealing mechanism pushes the moving sealing blade towards the stationary sealing blade. The serrated blade, fixedly connected to the inner side of the moving sealing blade, cooperates with the stationary sealing blade to heat-seal and cut the top of the packaging bag, completing the entire sealing process.

[0022] The above technical solution utilizes the following core design of the device: A circular track is designed with multiple sliders movably connected to it. Each slider connects to a different material guide channel, and flanges at the top of the guide channels connect to different material sources, enabling rapid switching between different products for packaging and sealing. In actual production, no large-scale disassembly and reinstallation of the equipment is required; simply adjusting the slider positions allows for quick product replacement, significantly saving time and costs and improving production efficiency. The secondary guide channel is extendable, allowing for precise length adjustment based on actual conditions. This ensures small parts accurately enter the bag-like structure formed inside the bag-guiding mechanism, guaranteeing bagging accuracy and preventing spillage or inaccurate bagging positions, thus improving product quality. This device achieves continuous operation from packaging film conveying, small part bagging, side sealing, film collection, to sealing. The components work together, with the drive motor driving the active roller to convey the packaging film, the bag guiding mechanism guiding the forming, the electric cylinder pushing the sealing element to complete the side sealing and sealing, and the film take-up roller handling the excess corners. The whole process is smooth and efficient, reducing intermediate stops and manual intervention, improving production efficiency and reducing production costs.

[0024] Preferably, in any of the above embodiments, the film receiving wheel is located behind the bag guide tube, directly below the side sealing mechanism.

[0025] Preferably, in any of the above embodiments, the sealing mechanism is horizontally arranged, and the inner side of the moving sealing knife is fixedly connected with a serrated blade.

[0026] Preferably, in any of the above embodiments, the annular track is made of stainless steel, and the top of the slider is threaded with a fastening pin, the bottom end of which abuts against the top surface of the annular track.

[0027] Preferably, as described in any of the above embodiments, the top of the guide channel is fixedly connected to a flange, and the end of the secondary channel can extend into the inside of the bag guiding mechanism.

[0028] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0029] This multi-segment collaborative continuous sealing device features a circular track with multiple movable sliders. Each slider connects to a different material guide channel, and flanges at the top of the guide channels connect to different material sources, enabling rapid switching between different products for packaging and sealing. When switching to packaging a different part, simply adjust the slider position to put the guide channel connected to that part's material source into the working position. This part then completes the sealing process according to the bagging, side sealing, film collection, and sealing flow. The entire process allows for rapid switching between different products for packaging and sealing, improving production efficiency. In actual production, there is no need for large-scale disassembly and reinstallation of the equipment; simply adjusting the slider position allows for quick product replacement, significantly saving time and costs and improving production efficiency. The secondary channel in the material guide channel is extendable, allowing for precise length adjustment according to actual conditions. This ensures that small parts accurately enter the bag-like structure formed inside the bag guide mechanism, guaranteeing bagging accuracy and preventing spillage or inaccurate bagging positions, thus improving product quality. This device enables continuous operation from packaging film conveying, small parts bagging, side sealing, film collection to sealing. All components work collaboratively: a drive motor drives an active roller to convey the packaging film, a bag guiding mechanism guides its formation, an electric cylinder pushes the sealing element to complete side sealing and sealing, and a film collection wheel handles excess edges and corners. The entire process is smooth and efficient, reducing intermediate stops and manual intervention, improving production efficiency, and lowering production costs.

[0046] Two film-taking rollers 14 are movably connected to the front of the machine body 1, and the film-taking rollers 14 are driven by a motor inside the machine body 1;

[0047] A sealing mechanism 15 is fixedly connected to the front of the machine body 1, an electric cylinder 11 is fixedly connected to the side of the sealing mechanism 15, a moving sealing knife 16 is fixedly connected to the output end of the electric cylinder 11, and a stationary sealing knife 17 is fixedly connected to the inner side of the sealing mechanism 15.

[0048] A bracket 18 is fixedly connected to the top of the machine body 1. A ring track 19 is fixedly connected to the top of the bracket 18. Several sliders 20 are movably connected to the outer surface of the ring track 19. The sliders 20 can be locked in position. When the fastening pins 23 on the sliders 20 are tightened, the ends of the fastening pins 23 press against the surface of the ring track 19, and the position of the sliders 20 is locked by the friction between the two. A guide channel 21 is fixedly connected to the front of the sliders 20. A secondary channel 22 is movably connected inside the guide channel 21. The secondary channel 22 is retractable.

[0049] The side of the guide channel 21 is threaded with a fastening pin 23, and the end of the fastening pin 23 abuts against the side of the auxiliary channel 22.

[0050] Example 1: The unwinding roller 3 is located above the driving roller 5, and the cross-sectional shape of the bag guiding mechanism 8 is arc-shaped. The side sealing mechanism 10 is vertically arranged, the bag guiding cylinder 9 is located directly in front of the side sealing mechanism 10, and the end face of the dynamic sealing element 12 is provided with an electric heating mechanism. The film taking-up roller 14 is located behind the bag guiding cylinder 9, and directly below the side sealing mechanism 10. The sealing mechanism 15 is horizontally arranged, and the inner side of the dynamic sealing knife 16 is fixedly connected with a serrated blade. The annular track 19 is made of stainless steel, and the top of the slider 20 is threadedly connected with a fastening pin 23, the bottom end of which abuts against the top surface of the annular track 19. The top of the guide channel 21 is fixedly connected with a flange, and the end of the auxiliary channel 22 can extend into the inner side of the bag guiding mechanism 8.

[0051] Example 2: The drive motor 4 starts, driving the drive roller 5 to rotate. The packaging film on the unwind roller 3 is conveyed by the cooperation of the drive roller 5 and the auxiliary roller 6, and is conveyed to the bag-guiding mechanism 8 along the inclined guide rod 7. The opening of the bag-guiding mechanism 8 gradually decreases from top to bottom, which guides and initially shapes the packaging film, gradually forming a bag-shaped structure suitable for inserting small parts.

[0052] Small parts bagging: Select the appropriate guide channel 21 according to different product requirements. The guide channel 21 is connected to different material sources through the flange at the top. Small parts enter the guide channel 21 from the material source, and then accurately enter the bag-shaped structure formed inside the bag guiding mechanism 8 through the retractable secondary channel 22 to complete the bagging operation.

[0053] Side sealing: The packaging bag containing small parts enters the side sealing mechanism 10. The electric cylinder 11 pushes the moving sealing element 12 to move towards the stationary sealing element 13. The electric heating mechanism on the end face of the moving sealing element 12 heats up. The end face of the moving sealing element 12 has a built-in heating wire that heats up when the power is turned on, so that when the moving sealing element 12 and the stationary sealing element 13 come into contact, the side of the packaging bag is heat-sealed, thus completing the side sealing process.

[0054] After the side sealing process, the two film receiving rollers 14, which are movably connected to the front of the machine body 1, are driven by the motor inside the machine body 1 to press the excess corners of the packaging film together. The packaged bag that has passed the side sealing enters the sealing mechanism 15. The electric cylinder 11 on the side of the sealing mechanism 15 pushes the moving sealing knife 16 to move towards the stationary sealing knife 17. The serrated blade fixedly connected to the inner side of the moving sealing knife 16 cooperates with the stationary sealing knife 17 to heat seal and cut the top of the packaged bag, completing the entire plastic sealing process.

[0055] The working principle of this utility model is as follows:

[0056] Two different types of small parts, A and B, need to be bagged and sealed. A suitable packaging film roll for small parts is installed on the unwind roller 3. For small part A, the pipe connecting the material source of small part A is connected to the flange at the top of the guide channel 21. The position of the slider 20 on the annular track 19 is adjusted so that the guide channel 21 is in the appropriate working position, and the slider 20 is locked. Simultaneously, the extension length of the secondary channel 22 is adjusted according to packaging requirements so that it can accurately penetrate the inside of the bag guiding mechanism 8. For small part B, similarly, the pipe connecting its material source is connected to the flange at the top of another guide channel 21, and the position of the slider 20 and the extension length of the secondary channel 22 are adjusted.

[0057] The drive motor 4 is turned on, driving the active roller 5 to rotate. The packaging film is conveyed from the unwinding roller 3 and, through the cooperation of the active roller 5 and the auxiliary roller 6, moves along the inclined guide rod 7 to the bag-guiding mechanism 8, initially forming a bag-shaped structure under the action of the bag-guiding mechanism 8. Small parts A are bagged and sealed: The guide channel 21 connected to the material source of small parts A is selected for operation. Small parts A enter the guide channel 21 from the material source and accurately enter the bag-shaped structure formed inside the bag-guiding mechanism 8 through the retractable auxiliary channel 22, completing the bagging. Next, the packaging bag containing small parts A enters the side sealing mechanism 10. The electric cylinder 11 pushes the dynamic sealing member 12 to move towards the static sealing member 13. The electric heating mechanism on the end face of the dynamic sealing member 12 heats up, heat-sealing the side of the packaging bag. Afterwards, the two film-receiving rollers 14 press the excess corners of the packaging film together, and the packaging bag enters the sealing mechanism 15. The electric cylinder 11 on the side of the sealing mechanism 15 pushes the moving sealing knife 16 to move towards the stationary sealing knife 17. The serrated blade cooperates with the stationary sealing knife 17 to heat seal and cut the top of the packaging bag, completing the plastic sealing of small part A.

[0058] Small Part B Packaging and Sealing: When switching to packaging small part B, simply adjust the slider 20 to position the guide channel 21 connecting to the material source of small part B in the working position. Small part B will then complete the sealing process according to the bagging, side sealing, film collection, and sealing procedures described for small part A. The entire process allows for rapid switching between packaging and sealing different products, improving production efficiency.

[0059] Compared with the prior art, the present invention has the following advantages:

[0060] This multi-segment collaborative continuous sealing device features a circular track 19 with multiple movable sliders 20 connected to it. Each slider 20 is connected to a different material guide channel 21, and the top of the material guide channel 21 has a flange for connecting different material sources, enabling rapid switching between different products for packaging and sealing. When switching to packaging a different component, simply adjust the position of the slider 20 to put the material guide channel connected to that component in the working position. This component then completes the sealing process according to the bagging, side sealing, film collection, and sealing flow. The entire process allows for rapid switching between different products for packaging and sealing, improving production efficiency. In actual production, there is no need for large-scale disassembly and reinstallation of the equipment; simply adjusting the position of the slider 20 allows for quick changes in the packaged product, significantly saving time and costs associated with product changeovers and further improving production efficiency. The secondary channel 22 in the guide channel 21 is extendable and its length can be accurately adjusted according to actual conditions. This allows small parts to accurately enter the bag-shaped structure formed inside the bag guiding mechanism 8, ensuring bagging accuracy and preventing spillage or inaccurate bagging positions, thus improving product quality. This device achieves continuous operation from packaging film conveying, small part bagging, side sealing, film collection, to sealing. All components work collaboratively: the drive motor 4 drives the active roller 5 to convey the packaging film, the bag guiding mechanism 8 guides the forming, the electric cylinder 11 pushes the sealing element to complete the side sealing and sealing, and the film collection wheel 14 handles excess edges and corners. The entire process is smooth and efficient, reducing intermediate stops and manual intervention, improving production efficiency, and lowering production costs.
