Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0026] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0028] For easier understanding, see Figure 1 and Figure 2The present embodiment provides an electromagnetic sealing machine, comprising a workbench 1, a lower sealing seat 2 is provided on the working surface of the workbench 1, a heating strip is provided inside the workbench 1, two sliding guide rails 3 are provided above the workbench 1, the sliding guide rails 3 are respectively slidably connected with the sliding bars 4 in the vertical direction, an upper sealing seat 5 is provided below the sliding bars 4, and the upper sealing seat 5 is located directly above the lower sealing seat 2, the left and right sides of the sliding bars 4 respectively penetrate the sliding guide rails 3 and are connected with transfer rods 6, and magnetic balls 7 with magnetism are respectively connected to the transfer rods 6, one end of a reset spring 8 is connected above the magnetic ball 7, and the other end of the reset spring 8 is connected to an extension plate 9, and the two extension plates 9 are respectively connected and fixed to the sliding guide rails 3, and the workbench 1 is respectively provided with electromagnet devices 10 at positions directly below the two magnetic balls 7. Place the packaging bag to be sealed on the lower sealing seat 2, turn on the power switch, and the two electromagnet devices 10 are magnetized when they are powered on at the same time. The two magnetic balls 7 are affected by the magnetic force and move vertically downward at the same time, driving the sliding bar 4 to slide downward on the sliding guide rail 3, so that the upper sealing seat 5 contacts the lower sealing seat 2, and the heating bar heats and softens the packaging bag to complete the sealing action of the packaging bag; turn off the power switch, the two electromagnet devices 10 are powered off and demagnetized, and the two magnetic balls 7 are pulled upward by the upper reset spring 8 to reset, driving the sliding bar 4 to slide upward on the sliding guide rail 3, so that the upper sealing seat 5 is separated from the lower sealing seat 2, and the sealed packaging bag can be taken out.

[0029] The workbench 1 is detachably connected to a limit baffle 11, and a limit block 12 for limiting the end of the packaging bag is provided on the limit baffle 11. The staff extends the end of the packaging bag from the angle between the limit block 12 and the limit baffle 11 to the bottom, so as to limit the packaging bag, ensure that the sealing position of the packaging bag is flush with the end of the packaging bag, and avoid the staff placing the packaging bag on the lower sealing seat 2. The sealing position is offset due to no limit, which affects the sealing effect of the sealing and the appearance of the product. The limit baffle 11 is provided with threaded holes on the left and right sides, and a plurality of through holes 13 are provided on the workbench 1 accordingly. The staff can adjust the position of the limit baffle 11 on the workbench 1 according to the actual distance between the sealing position of the packaging bag and the end of the packaging bag, and pass the screw 14 through the through hole 13 of the workbench 1 and the threaded hole of the limit baffle 11 in turn, and lock the screw 14 to achieve the relative fixation of the limit baffle 11 and the workbench 1.

[0030] The limit baffle 11 is provided with an infrared sensor 15, which is electrically connected to the electromagnet device 10. The infrared sensor 15 can detect whether the packaging bag extends under the limit block 12. When the infrared sensor 15 detects that the end of the packaging bag extends under the limit block 12, it sends an electrical signal to the two electromagnet devices 10, and the electromagnet devices 10 start with a delay, and are powered to generate magnetism, so that the sliding bar 4 drives the upper sealing seat 5 to slide downward to perform the sealing action, thereby realizing semi-automatic sealing and improving the sealing efficiency of the staff.

[0031] A water cooling pipe for cooling the heating strip is arranged in the lower sealing seat 2, and a water cooling box 16 is arranged under the workbench 1. The water inlet and outlet of the water cooling pipe are respectively connected with a water delivery pipe 17, and the water delivery pipe 17 is connected with the water cooling box 16 for circulating water. After completing a sealing action, by circulating cold water in the water cooling pipe, the cooling rate of the heating strip is accelerated, the interval time for the next sealing is reduced, and the sealing efficiency is further improved.

[0032] A purification box is provided below the workbench 1. The purification box is provided with an air pump and an adsorbent for purifying the air. The adsorbent can be activated carbon. Two suction tubes 18 are provided above the workbench 1. The suction tubes 18 are connected to the air pumps through air supply pipes. A protective mesh cover 19 is provided at the air inlet of the suction tubes 18 to prevent other objects from being sucked into the suction tubes 18 and causing pipe blockage. During the sealing operation, since the packaging bag is made of plastic material, it will decompose and produce toxic plasticized gas with a pungent odor after heating. By providing suction tubes 18 on the left and right sides of the upper and lower sealing seats 2 of the workbench 1, the gas generated during sealing can be sucked into the purification box below the workbench 1, and the sucked gas can be purified by the adsorbent and then discharged, avoiding harm to the staff who work at the sealing station for a long time.

[0033] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
