[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a synchronous sealing device for a trayless pastry packaging machine, comprising a carrier 1 and a connecting platform 11. The carrier 1 provides fixation and support for the upper device. An adjustment component for adjusting the height of the sealing device is fixedly connected to the top right side of the carrier 1. The adjustment component is used to adjust the height of the sealing device. A connecting rod 2 is threadedly connected to the external part of the adjustment component. The connecting rod 2 provides fixation and support for the carrier box 3 and the fixing block 20. The carrier box 3 is fixedly connected to the top of the connecting rod 2. The carrier box 3 provides installation space and protection for the internal cleaning component. A cylinder 4 is fixedly connected to the inner top of the carrier box 3. The cylinder 4 is the power source for the cleaning component. A U-shaped frame 5 is fixedly connected to the drive end of the cylinder 4. The U-shaped frame 5 moves under the force from the cylinder 4.

[0034] Connecting blocks 6 are fixedly connected to the bottom left and right sides of the U-shaped frame 5, thereby moving the connecting blocks 6. The connecting blocks 6 have a sliding groove 7 inside, which provides fixation and support for the springs 8. Multiple springs 8 are fixedly connected to the right side of the inner wall of one of the sliding grooves 7. The springs 8 have elasticity and provide fixation and support for the trapezoidal block 9. The trapezoidal block 9 is fixedly connected to the left side of the multiple springs 8. The trapezoidal block 9 matches the outer slope of the fixed block 20. A scraper 10 is fixedly connected to the left side of the trapezoidal block 9. The scraper 10 is used to clean the exterior of the fixed block 20 and the heat sealing strip 21. The connecting platform 11 has a portable component for easy tension adjustment inside.

[0035] Reference Figure 3 and Figure 5The portable component includes a second slide groove 12, which provides limiting and guiding functions for the connecting block 14. Multiple limiting grooves 13 are provided inside the connecting platform 11, i.e., on the left and right sides of the second slide groove 12. These limiting grooves 13 cooperate with the trapezoidal block 19 to achieve limiting and fixing functions. The connecting block 14 is slidably connected inside the second slide groove 12. The connecting block 14 is the main component for adjusting the tension of the tension roller 22. An adjusting knob 15 is threaded inside the connecting block 14. Rotating the adjusting knob 15 presses the outer inclined surface of the trapezoidal block 19. The connecting block 14 has multiple limiting grooves 13 on its left and right sides. A slide groove 3 16 is provided, which provides fixation and support for spring 2 17. Two springs 2 17 are fixedly connected to the left side of the inner wall of one of the slide grooves 3 16. After the force of the adjustment knob 15 disappears on the trapezoidal block 2 19, the spring 2 17 pulls the slider 18 to reset through its own elasticity. The slider 18 is fixedly connected to the right side of the spring 2 17, and then the slider 18 pulls the trapezoidal block 2 19 to automatically reset. The trapezoidal block 2 19 is fixedly connected to the adjacent side of the two sliders 18. Similarly, the limiting groove 13 is used to cooperate with the trapezoidal block 2 19 to complete the limiting and fixing function.

[0036] Reference Figures 1 to 3 The bottom of the connecting rod 2 is fixedly connected to a fixing block 20, which provides a fixing and connection function for the fixing block 20. The bottom of the fixing block 20 is fixedly connected to a heat sealing strip 21, which provides a fixing and support function for the heat sealing strip 21. The adjustment component includes a fixing box 24, which provides installation space and fixation function for the adjustment component. The top of the fixing box 24 is fixedly connected to a motor 25, which is the power source for the adjustment component. The drive end of the motor 25 is fixedly connected to a threaded rod 26, which receives force from the motor 25 to rotate. The outer rear side of the connecting rod 2 is threadedly connected to the outside of the threaded rod 26, so that the connecting rod 2 receives force from the threaded rod 26 to adjust its height. The outer side of the trapezoidal block 9 is slidably connected to the inside of the slide groove 7, which provides a limiting and guiding function for the trapezoidal block 9. The outer left side of the scraper 10 is in contact with the outside of the fixing block 20, and the scraper 10 cleans the outside of the fixing block 20 and the heat sealing strip 21.

[0037] Tension roller 22 is fixedly connected to the rear side of connecting block 14. Connecting block 14 facilitates the movement of tension roller 22 to adjust tension. Control console 23 is fixedly connected to the top rear side of carrier 1. Control console 23 is used to control various parameters of the device. Conveyor 28 is provided on the left side of carrier 1. Conveyor 28 is used to transport unsealed pastries. Connecting platform 27 is fixedly connected to the left side of control console 23. Connecting platform 27 is used to fix and support multiple fixed rollers. The rear side of tension roller 22 is slidably connected to the inside of connecting platform 27, providing limiting and guiding functions for tension roller 22. The outside of adjustment knob 15 contacts the adjacent side of two trapezoidal blocks 19. By rotating adjustment knob 15, the outer inclined surface of two trapezoidal blocks 19 is squeezed, so that they can slide and be inserted into the inside of limiting groove 13. The outside of slide groove 12 is opened inside connecting platform 11. Connecting platform 11 provides opening space for slide groove 12.

[0038] Working principle: When the sealing device needs to be cleaned, the cylinder 4 is activated, which moves the U-shaped frame 5 downward. The U-shaped frame 5 then moves the connecting block 6 downward, which in turn moves the trapezoidal block 9 within the slide groove 7. The trapezoidal block 9, through the elastic action of the spring 8, adheres tightly to the outside of the fixed block 20. This allows the scraper 10 to clean the outside of the fixed block 20 and the heat sealing strip 21, removing residual impurities and ensuring sealing quality.

[0039] When the tension of the tension roller 22 needs to be adjusted, the operator rotates the adjustment knob 15, which presses the inclined surface of the trapezoidal block 19. This causes the slider 18 to slide within the groove 16, stretching the spring 17. The trapezoidal block 19 then engages with different positions of the limiting groove 13, thus adjusting the position of the connecting block 14. Since the tension roller 22 is connected to the rear of the connecting block 14, the position of the tension roller 22 changes accordingly as the position of the connecting block 14 changes, thereby adjusting the tension of the pastry packaging material to meet different packaging needs and ensure a smooth packaging process.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
