The base plate 1 can be made of metal, such as stainless steel, which has advantages such as high strength and corrosion resistance, and can withstand the weight of the various components of the device as well as external forces during use. The adjustment assembly is mounted on the base plate 1, and the sealing assembly is mounted on the adjustment assembly.

[0024] Furthermore, the adjustment assembly includes a crossbeam 5, a telescopic motor 6, a cross plate 7, a positioning unit, and two uprights 4. The two uprights 4 are vertically mounted on the upper surface of the base plate 1, symmetrically arranged on the left and right sides of the groove 3, respectively. The uprights 4 can be made of metal, such as aluminum alloy, which is lightweight and high-strength. The crossbeam 5 is horizontally positioned between the two uprights 4, with its left and right ends fixedly connected to the upper inner sides of the two uprights 4. The crossbeam 5 can be connected by welding or bolts to ensure a secure connection. The crossbeam 5 provides an installation position for the telescopic motor 6. Two vertical grooves 8 are provided on the inner sides of the two columns 4 respectively. The grooves 8 provide guidance for the vertical movement of the horizontal plate 7. The horizontal plate 7 is horizontally set between the two columns 4 and below the crossbeam 5. The left and right ends of the horizontal plate 7 are slidably connected to the corresponding grooves 8 on the inner sides of the two columns 4 respectively. The telescopic motor 6 is set in the middle of the upper end face of the crossbeam 5. The output end of the telescopic motor 6 passes vertically downward through the crossbeam 5 and is fixedly connected to the middle of the upper end face of the horizontal plate 7. The telescopic motor 6 can be an electric push rod. It realizes telescopic movement by energizing and drives the horizontal plate 7 to move up and down, thereby adjusting the distance between the positioning unit and the upper edge of the food packaging. The telescopic motor 6 drives the horizontal plate 7 to move up and down. The positioning unit is set on the lower end face of the horizontal plate 7 along the length direction of the horizontal plate 7 and is used to position and fix the upper edge of the food packaging.

[0025] Furthermore, the positioning unit includes a pressure plate 9, a front plate 10, and a positioning plate 11. The pressure plate 9 is vertically arranged at the rear end of the lower end face of the horizontal plate 7 along the length direction of the horizontal plate 7. The pressure plate 9 can be made of plastic and has a certain degree of flexibility and wear resistance. The front plate 10 is vertically arranged at the front end of the lower end face of the horizontal plate 7 along the length direction of the horizontal plate 7. The positioning plate 11 is hinged to the lower end face of the front plate 10 along the length direction of the front plate 10. The positioning plate 11 is provided with a handle 14 to facilitate the operator to rotate the positioning plate 11. The front end face of the pressure plate 9 is provided with a positioning groove 13 horizontally along the length direction of the pressure plate 9. The rear end face of the positioning plate 11 is provided with a positioning strip 12 horizontally along the length direction of the positioning plate 11. The positioning strip 12 is configured and used in conjunction with the positioning groove 13. When the positioning plate 11 is rotated to be parallel with the pressure plate 9, the positioning strip 12 is embedded in the positioning groove 13, fixing the upper edge of the food packaging between the positioning plate 11 and the pressure plate 9. A molding groove 15 is horizontally provided at the lower end of the front face of the pressure plate 9 along the length of the pressure plate 9, for use with the molding assembly to perform molding operations.

[0026] Furthermore, a heat insulation pad 16 is provided on the inner wall of the molding groove 15. The heat insulation pad 16 can be made of silicone, which has good heat insulation performance and prevents the heat generated during the molding process from being transferred to the pressure plate 9, affecting the positioning effect and the safety of the operator.

[0027] Furthermore, the molding assembly includes a vertical plate 18, a molding head 21, and two electric telescopic rods 20. The front ends of the two columns 4 are each vertically provided with a second sliding groove 17 to guide the vertical movement of the vertical plate 18. The vertical plate 18 is horizontally positioned above the base plate 1 and at the front end of the two columns 4. The left and right ends of the vertical plate 18 are respectively slidably limited to the second sliding groove 17 on the two columns 4 to ensure the stability of the vertical plate 18 during vertical movement. The rear end face of the vertical plate 18 is symmetrically provided with two electric telescopic rods 20. Both electric telescopic rods 20 are horizontally positioned, and their fixed ends are fixedly connected to the rear end face of the vertical plate 18. The two electric telescopic rods 20 can be connected by bolts. The electric telescopic rod 20 can be a stepper motor driven push rod, which can achieve precise telescopic control. The telescopic ends of the two electric telescopic rods 20 are fixedly connected to the sealing head 21, which is horizontally set at the rear end of the vertical plate 18 along the length direction of the vertical plate 18. The two electric telescopic rods 20 synchronously drive the sealing head 21 to move back and forth. The sealing head 21 is matched and used in conjunction with the sealing groove 15 at the lower end of the front face of the pressure plate 9. The sealing head 21 is equipped with a heating rod. When the heating rod is powered on, it heats up, which raises the surface temperature of the sealing head 21. When the sealing head 21 contacts the upper edge of the food packaging, the sealing operation is realized. The left and right ends of the front face of the vertical plate 18 are respectively equipped with handles 19, which facilitate the operator to move the vertical plate 18.

[0028] I. Equipment Installation:

[0029] Place the base plate 1 on a suitable workbench. Use bolts to fix the base plate 1 to the workbench through the mounting threaded holes 2 at the four corners of the base plate 1, ensuring that the base plate 1 is firmly installed without shaking.

[0030] Two uprights 4 are vertically installed on the left and right sides of the groove 3 on the upper surface of the base plate 1. The two uprights 4 can be connected by welding or bolts to ensure that the uprights 4 are perpendicular to the base plate 1 and the connection is stable.

[0031] The crossbeam 5 is installed horizontally between the two columns 4, with the left and right ends of the crossbeam 5 fixedly connected to the upper inner sides of the two columns 4 respectively. The crossbeam 5 can be connected by welding or bolts to ensure that the crossbeam 5 is installed horizontally.

[0032] Install the telescopic motor 6 in the middle of the upper end face of the crossbeam 5, so that the output end of the telescopic motor 6 passes vertically downward through the crossbeam 5.

[0033] Place the horizontal plate 7 horizontally between the two columns 4, so that the left and right ends of the horizontal plate 7 are slidably connected to the corresponding sliding grooves 8 on the inner side of the two columns 4, and then fix the output end of the telescopic motor 6 to the middle of the upper end face of the horizontal plate 7.

[0034] Install the positioning unit, vertically install the pressure plate 9 along the length of the horizontal plate 7 at the rear end of the lower end face of the horizontal plate 7, vertically install the front plate 10 along the length of the horizontal plate 7 at the front end of the lower end face of the horizontal plate 7, and then hinge the positioning plate 11 to the lower end face of the front plate 10.

[0035] Vertical grooves 17 are vertically installed on the front surfaces of the two columns 4. The vertical plate 18 is placed horizontally above the base plate 1 and at the front of the two columns 4, so that the left and right ends of the vertical plate 18 are respectively connected to the sliding grooves 17 on the two columns 4 for sliding and limiting.

[0036] Two electric telescopic rods 20 are symmetrically installed on the left and right sides of the rear end face of the vertical plate 18. The sealing head 21 is horizontally installed on the telescopic ends of the two electric telescopic rods 20, ensuring that the sealing head 21 corresponds to the sealing groove 15 at the lower end of the front face of the pressure plate 9.

[0037] Install the heating rod inside the sealing head 21 and connect the power supply line.

[0038] II. Working Principle:

[0039] Positioning Stage: The operator places the food packaging to be sealed into the groove 3 of the base plate 1. Based on the size and shape of the food packaging, the operator starts the telescopic motor 6. The output end of the telescopic motor 6 extends and retracts, causing the horizontal plate 7 to move up and down along the slide groove 8, thereby adjusting the height of the positioning unit so that it accurately aligns with the upper edge of the food packaging. Then, the operator holds the handle 14 on the positioning plate 11 and rotates it, causing the positioning strip 12 on the rear end face of the positioning plate 11 to embed into the positioning groove 13 on the front end face of the pressure plate 9, fixing the upper edge of the food packaging between the positioning plate 11 and the pressure plate 9, achieving precise positioning of the food packaging.

[0040] Sealing Stage: After the food packaging is positioned, the operator holds the handle 19 on the vertical plate 18 and moves the vertical plate 18 along the slide 17 to the appropriate position, aligning the sealing head 21 with the sealing groove 15 at the lower end of the front face of the pressure plate 9. Then, the two electric telescopic rods 20 are activated, extending and retracting synchronously, driving the sealing head 21 forward until it contacts the upper edge of the food packaging. Simultaneously, the heating rod inside the sealing head 21 is energized, raising the surface temperature of the sealing head 21 and sealing the food packaging. After sealing, the electric telescopic rods 20 drive the sealing head 21 backward, detaching it from the food packaging.

[0041] Reset phase: The operator rotates the positioning plate 11 again to separate it from the pressure plate 9 and removes the sealed food packaging. Then, the positions of the various components of the device can be adjusted as needed to prepare for the next sealing operation.

[0042] III. Work Process:

[0043] First, place the food packaging in the groove 3 of the base plate 1. Start the telescopic motor 6 and observe the movement of the horizontal plate 7, lowering the positioning unit to a suitable height to ensure that the pressure plate 9 and positioning plate 11 cover the upper edge of the food packaging. Next, rotate the positioning plate 11 to fix the upper edge of the food packaging between the positioning plate 11 and the pressure plate 9. Then, move the vertical plate 18 to align the sealing head 21 with the sealing groove 15 at the lower end of the front face of the pressure plate 9. Start the electric telescopic rod 20 to move the sealing head 21 forward and contact the upper edge of the food packaging, while simultaneously turning on the heating rod power to perform sealing. After sealing, the electric telescopic rod 20 drives the sealing head 21 backward, rotates the positioning plate 11, and removes the sealed food packaging. The entire process is simple to operate, highly efficient, and ensures sealing quality.

[0044] The plastic sealing device of this invention has a simple and reasonable structure, is easy to operate, and can be flexibly adjusted according to food packaging of different sizes and shapes to achieve efficient and high-quality plastic sealing operations, thereby improving the efficiency of food processing and product quality.
