Description

An automatic bagging and sealing mechanism for down pillows Technical Field

[0001] This utility model relates to the field of down pillow packaging technology, specifically an automatic bagging and sealing mechanism for down pillows. Background Technology

[0002] The heat-sealing mechanism after down pillow packaging is primarily responsible for sealing the bags to prevent leakage or contamination of the down during transportation and storage, ensuring product quality and hygiene. It consists of main components such as a heating plate or heating roller, a pressure control system, a transport mechanism, a control system, and safety devices. Its working principle involves the heating plate fusing the packaging material at the bag opening under preset temperature and pressure to form a strong seal. Before sealing, the down is placed into the bag, ensuring the bag opening is flat and aligned, and then placed in the heat-sealing equipment for heating and sealing. During the heating process, the equipment controls the temperature and pressure to ensure a tight and flawless seal, forming a strong seal line after cooling. The entire sealing process includes several steps: preparation, alignment, heat sealing, cooling and curing, and quality inspection. However, current sealing mechanisms are generally large in size and often use rigid materials and fixed connection methods, such as bolt fixing and welding. Once the debugging is completed, the relative position of the heat sealing plate is fixed, making it quite difficult to adjust the heat sealing position later. If it is necessary to change the size of the packaging bag or adjust the position of the sealing line, it is often necessary to disassemble the equipment or perform complex debugging. This greatly reduces the adaptability of the equipment and limits the diversification of the production line. Summary of the Invention

[0003] The purpose of this utility model is to provide an automatic bagging and sealing mechanism for down pillows. The down pillow and the opening of the packaging bag to be heat-sealed are placed between the upper heat-sealing plate and the lower heat-sealing plate. The eccentric servo pressing assembly at the top of the U-shaped housing drives the support plate, elastic element, and upper heat-sealing plate to move down until the opening of the packaging bag is heat-sealed. After heat sealing, the upper heat-sealing plate is reset. When the heat sealing position is adjusted, the cylinder drives the support plate, elastic element, upper heat-sealing plate, and lower heat-sealing plate to move together to change the heat sealing position, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic bagging and sealing mechanism for down pillows, comprising a U-shaped housing, a support plate slidably mounted inside the U-shaped housing in the Z-axis direction, and an eccentric servo pressing assembly at the top of the U-shaped housing for driving the support plate to slide along the Z-axis. A cylinder is mounted on one side of the top of the support plate, and a sliding plate is fixed to the top of the piston rod of the cylinder. The sliding plate and the support plate are slidably engaged. Elastic elements are mounted on both sides of the bottom end of the sliding plate, and an upper heat-sealing plate is mounted on the lower end of the two elastic elements. A slide table is slidably mounted on the bottom of the U-shaped housing, and a lower heat-sealing plate is mounted on the upper surface of the slide table. A telescopic column is fixed between the top of the slide table and the bottom of the sliding plate. A control panel electrically connected to the input ends of the eccentric servo pressing assembly, the cylinder, the upper heat-sealing plate, and the lower heat-sealing plate is mounted on one outer wall of the U-shaped housing.

[0005] Preferably, the support plate has a perforated window inside for the telescopic column to move horizontally.

[0006] Preferably, the eccentric servo pressing assembly includes a servo motor mounted on one side of the top of the U-shaped housing, a rotating shaft mounted on the end of the servo motor drive shaft via a coupling, and columns slidably mounted on both sides inside the U-shaped housing. The bottom end of the column is fixedly connected to one side of the outer wall of the support plate. A raised plate is fixed to the top of the two columns. The raised plate has a straight groove inside, and an eccentric wheel is provided inside the straight groove. One end of the eccentric wheel is fixedly connected to one end of the rotating shaft.

[0007] Preferably, the elastic element includes an I-beam fixed at both ends inside the slide plate, a connecting beam slidably mounted on the two I-beams, and a spring fitted on the outer circumference of the I-beams above the connecting beams, and the upper heat-sealing plate is installed at the bottom end of the connecting beams.

[0008] Preferably, the column is made of stainless steel.

[0009] Preferably, both sides of the bottom of the U-shaped housing are integrally formed with rectangular tracks, and the rectangular tracks and the slide table slide in a sliding fit.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic bagging and sealing mechanism for down pillows is equipped with a control panel, a U-shaped housing, an eccentric servo pressing assembly, a support plate, an elastic element, an upper heat-sealing plate, and a lower heat-sealing plate, which work together. The bag containing the down pillow and the opening of the packaging bag to be heat-sealed are placed between the upper and lower heat-sealing plates. The eccentric servo pressing assembly at the top of the U-shaped housing drives the support plate, elastic element, and upper heat-sealing plate to move downwards until the bag opening is heat-sealed. After heat-sealing, the upper heat-sealing plate returns to its original position. When adjusting the heat-sealing position, a cylinder drives the support plate, elastic element, upper heat-sealing plate, and lower heat-sealing plate to move together to change the heat-sealing position. The mechanism further enhances the sealing capabilities of the packaging bag. The bag opening is placed between the upper and lower heat-sealing plates. An eccentric servo pressing assembly drives the support plate and the upper heat-sealing plate to move as a whole. At this time, the support plate, elastic element and upper heat-sealing plate move synchronously as a whole, avoiding the deviation or misalignment problems that may be caused by adjusting a single part, thus ensuring the precise position of the sealing line. When adjusting the heat-sealing position of the upper and lower heat-sealing plates, the movement of the slide plate and heat-sealing plate is driven by a cylinder. The movement of the cylinder can be adjusted as needed to adapt to packaging bags of different sizes or positions, so that the production line can better cope with diverse packaging needs, reduce the frequency of equipment or mold changes and save production costs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please refer to Figures 1-5. One embodiment of this utility model is an automatic bagging and sealing mechanism for down pillows, including a U-shaped housing 1, a support plate 2 slidably installed inside the U-shaped housing 1 in the Z-axis direction, and an eccentric servo pressing assembly 3 at the top of the U-shaped housing 1 for driving the support plate 2 to slide in the Z-axis direction. A cylinder 4 is installed on one side of the top of the support plate 2. A slide plate 5 is fixed to the top of the piston rod of the cylinder 4. The slide plate 5 and the support plate 2 are slidably engaged. Elastic members 6 are installed on both sides of the bottom of the slide plate 5. An upper heat sealing plate 7 is installed at the lower end of the two elastic members 6. A slide table 8 is slidably installed at the bottom of the U-shaped housing 1, and a lower heat sealing plate 9 is installed on the upper surface of the slide table 8. Rectangular tracks are integrally formed on both sides of the bottom of the U-shaped housing 1. The rectangular tracks and the slide table 8 are slidably engaged.

[0019] A telescopic column 11 is fixed between the top of the slide table 8 and the bottom of the slide plate 5. The telescopic column 11 assists the slide plate 5, support plate 2, elastic element 6, upper heat sealing plate 7, and cylinder 4 in raising and lowering. On the other hand, it is used to connect the slide table 8 and slide plate 5 to ensure that the two can move together under the drive of cylinder 4. A control panel 10 is installed on one outer wall of the U-shaped housing 1 and is electrically connected to the input end of the eccentric servo pressing assembly 3, cylinder 4, upper heat sealing plate 7, and lower heat sealing plate 9.

[0020] The support plate 2 is provided with a perforated window 201 for the telescopic column 11 to move horizontally;

[0021] The eccentric servo pressing assembly 3 includes a servo motor 301 mounted on one side of the top of the U-shaped housing 1, a rotating shaft 302 mounted on the end of the drive shaft of the servo motor 301 via a coupling, and columns 303 slidably mounted on both sides inside the U-shaped housing 1. The bottom end of the column 303 is fixedly connected to one side of the outer wall of the support plate 2. The column 303 is made of stainless steel. The top of the two columns 303 is fixed with a raised plate 304. The raised plate 304 has a straight groove 306 inside. The straight groove 306 has an eccentric wheel 305 inside. One end of the eccentric wheel 305 is fixedly connected to one end of the rotating shaft 302.

[0022] When the eccentric servo pressing assembly 3 is working, the drive shaft of the servo motor 301 drives the rotating shaft 302 and the eccentric wheel 305 to rotate through the coupling. Since the eccentric wheel 305 is located in the straight groove 306 of the convex plate 304, the eccentric wheel 305 will force the convex plate 304, the column 303, the support plate 2, the slide plate 5, the cylinder 4, the elastic element 6, and the upper heat sealing plate 7 to move down until the upper heat sealing plate 7 and the lower heat sealing plate 9 press the bag opening of the packaging bag and complete the heat sealing.

[0023] The elastic element 6 includes an I-beam fixed at both ends inside the slide plate 5, a connecting beam slidably mounted on the two I-beams, and a spring fitted on the outer circumference of the I-beams above the connecting beam. The upper heat sealing plate 7 is installed at the bottom of the connecting beam. The elastic element 6 can absorb the vibration and pressure changes generated during the sealing process, ensure the uniform distribution of pressure, and prevent poor sealing or bag deformation caused by uneven pressure.

[0024] In this embodiment, the worker first tidies up the opening of the down pillow packaging bag to be sealed and places it between the upper heat-sealing plate 7 and the lower heat-sealing plate 9, ensuring the bag opening is flat and correctly aligned for subsequent heat-sealing operations. Then, the eccentric servo pressing assembly 3 is activated via the control panel 10. The eccentric servo pressing assembly 3 drives the support plate 2, cylinder 4, slide plate 5, elastic element 6, and upper heat-sealing plate 7 to move downwards, gradually applying pressure. The upper and lower heat-sealing plates 7 and 9 clamp the bag opening in the sealing area. The upper and lower heat-sealing plates 7 and 9 are heated to the set temperature, ensuring the bag opening remains between the heat-sealing plates for a sufficient time to complete the seal. After sealing, the eccentric servo pressing assembly 3 drives the upper heat-sealing plate 7 to gradually return upwards, releasing the pressure between the upper and lower heat-sealing plates 7 and 9. At this time, the elastic element 6 also returns to its original position, ready for the next sealing operation. After the upper and lower heat-sealing plates 7 and 9 separate, the worker can remove the packaging bag.

[0025] When adjusting the heat-sealing position of the upper heat-sealing plate 7 and the lower heat-sealing plate 9, the operator activates the cylinder 4 through the control panel 10. The cylinder 4 pushes the slide plate 5 and the upper heat-sealing plate 7 away from the U-shaped housing 1. Since the slide plate 5 and the slide table 8 are connected by the telescopic column 11, the slide table 8 and the lower heat-sealing plate 9 move away from the U-shaped housing 1 together, so that the upper heat-sealing plate 7 and the lower heat-sealing plate 9 move synchronously, thereby adjusting the heat-sealing position of the upper heat-sealing plate 7 and the lower heat-sealing plate 9 on the opening of the packaging bag.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
