The conventional container inner lining bag has 20 feet and 40 feet, and the lifting ring used in 20 feet container is about 10, and the lifting ring used in 40 feet container is about 20. In the preparation of the inner lining bag on the market, only the feeding rack, tensioning mechanism, sealing heat sealing mechanism and traction device are used to produce single inner lining bag, and the lifting ring needs to be heat sealed on the produced inner lining bag for later use of the inner lining. In the existing production technology process, the lifting ring on the inner lining bag is heat sealed to the inner lining bag by manually holding the heat sealing device. In the process of heat sealing the lifting ring, the production personnel need to walk back and forth with the manual heat sealing tool. This process is time-consuming and laborious, and requires a lot of labor from the workers. Because it is manually heat sealed, the heat sealing time and position of the lifting ring cannot be accurately controlled, which may cause the heat sealed lifting ring to be not firm and the heat sealing point to not meet the requirements, which cannot guarantee the product quality and also reduces the production efficiency. On the other hand, because it is manually heat sealed, it may also cause the lifting ring to be missed, which affects the final quality of the finished inner lining bag.

[0041] It should be noted that, as shown in Figure 2 and Figure 3 in a specific embodiment of the present application, the lifting ring heat sealing head 34 comprises a heating head 346 and a telescopic cylinder 341 for driving the heating head 346 to move, wherein in the specific embodiment, the telescopic cylinder 341 is an electric cylinder, and the telescopic rod part of the telescopic cylinder 341 is vertically arranged and perpendicular to the working platform 32; in addition, the telescopic cylinder 341 is fixed on the sliding block of the electric sliding rail 33, so that the sliding block on the electric sliding rail 33 drives the telescopic cylinder 341 to move horizontally; in addition, a base 345 for mounting the heating head 346 is fixed at the bottom end of the telescopic rod of the telescopic cylinder 341, the base 345 is made of high-temperature-resistant material to avoid deformation caused by the temperature on the heating head 346; the base 345 is driven to move vertically by the telescopic cylinder 341, and the heating head 346 is driven to move vertically, so that the heating head 346 can take and heat seal the lifting ring 6, reducing manual operation.

[0042] Further, referring to Figure 3 , Figure 4 and Figure 7 , in a specific embodiment of the present application, the heating head 346 is a top-sealed cylindrical structure, the top surface of which is fixed to the bottom surface of the base 345, and an electric heating element 349 for providing heat to the heating head 346 is fixed to the circumferential side wall of the heating head 346. The overall temperature of the heating head 346 is raised by the electric heating element 349, and the heat sealing requirement is met. In addition, the outer diameter of the heating head 346 is smaller than the outer diameter of the laminating film 601 on the hanging ring 6, and the inner diameter of the heating head 346 is larger than the inner diameter of the laminating film 601. The laminating film 601 on the hanging ring 6 is heated by the heating head 346 to be heat sealed to the PE film.

[0043] It should be noted that, referring to Figure 3 and Figure 4 , in a specific embodiment of the present application, a through hole 3461 is formed in the sealed top of the heating head 346, and the through hole 3461 penetrates the sealed top of the heating head 346. In addition, a mounting hole 3451 is formed in the base 345, the diameter of the mounting hole 3451 is smaller than the diameter of the through hole 3461, and the mounting hole 3451 and the through hole 3461 are coaxially arranged, the mounting hole 3451 penetrates the base 345 and is in communication with the through hole 3461. A suction pipe 347 is fixed in the mounting hole 3451, and the suction pipe 347 is sealingly and fixedly connected with the mounting hole 3451, thereby fixing the position of the suction pipe 347. In addition, the suction pipe 347 penetrates the mounting hole 3451 and the through hole 3461, the bottom end of the suction pipe 347 is flush with the bottom surface of the heating head 346, and the bottom end of the suction pipe 347 is in contact with the laminating film 601 in the hanging ring 6. A gas pump 38 is connected to the top end of the suction pipe 347, and the gas pump 38 is fixed to the side wall of the telescopic cylinder 341 through a connecting block 39, so that the gas pump 38 can displace synchronously with the telescopic cylinder 341. The gas pump 38 and the suction pipe 347 are connected by a gas pipe 348, and the gas pipe 348 is made of soft material. The suction pipe 347 is provided with suction force by the gas pump 38. When the bottom end of the suction pipe 347 is in contact with the hanging ring 6, the gas pump 38 is started and the air in the suction pipe 347 is pumped out through the gas pipe 348, so that the suction pipe 347 is in a negative pressure state, and the hanging ring 6 is adsorbed to the bottom end of the suction pipe 347 under the action of the gas pressure. When the heating head 346 and the base 345 move, the suction pipe 347 and the hanging ring 6 are driven to move.

[0044] Referring to Figure 5 and Figure 6As shown in the specific embodiment of the present application, the lifting ring placing rack 36 comprises a vertical limiting support rod 361 and a lifting ring limiting rod 364, and a placing platform 363 for storing a plurality of lifting rings 6. The placing platform 363 is positioned below the lifting ring heat sealing head 34 and corresponds to the lifting ring heat sealing head 34, so that the lifting ring heat sealing head 34 can accurately take the lifting ring 6 from the placing platform 363. In addition, the placing platform 363 is fixed on the limiting support rod 361 by a limiting block 362. The two side ends of the limiting block 362 are fixedly connected with the side wall of the placing platform 363 and the limiting rod 361, so as to limit the position of the placing platform 363 and prevent the lifting ring heat sealing head 34 from damaging the placing platform 363 when taking the lifting ring 6. In addition, the bottom end of the lifting ring limiting rod 364 is fixed on the rack 31 by a connecting seat 365, and the position of the lifting ring limiting rod 364 corresponds to the lifting ring heat sealing head 34. An opening is formed in the placing platform 363 for the lifting ring limiting rod 364 to pass through. The top end of the lifting ring limiting rod 364 protrudes above the top surface of the placing platform 363 after passing through the opening. It should be noted that, as shown in Figure 5 and Figure 7 The pulling rope 602 on the lifting ring 6 divides the inner ring of the adhered film 601 into two parts. The lifting ring limiting rod 364 is provided with two lifting ring limiting rods 364 for sleeving the lifting ring 6. The position of the lifting ring 6 is limited by sleeving the lifting ring 6 on the lifting ring limiting rod 364, so that the accumulated lifting ring 6 will not be offset or collapsed when the lifting ring heat sealing head 34 sucks the lifting ring 6. It should be noted that the height of the top end of the lifting ring limiting rod 364 protruding above the placing platform 363 is slightly less than the inner cavity depth of the heating head 364, so as to avoid the top end of the lifting ring limiting rod 364 from contacting the heating head 364 and prevent damage caused by collision and extrusion.

[0045] Further, as shown in Figure 3 In a specific embodiment of the present application, a vertical guide rail 3411 is fixed on the outer wall of the telescopic cylinder 341, and a sliding plate 342 is slidably installed on the guide rail 3411. A sliding groove matching the guide rail 3411 is formed in the sliding plate 342, so that the sliding plate 342 can move in the vertical direction along the guide rail 3411. In addition, a horizontal push-pull plate 344 is fixed on the bottom of the sliding plate 342, and the top surface of the push-pull plate 344 is fixedly connected with the end of the telescopic rod of the telescopic cylinder 341. In addition, a vertical connecting plate 343 is fixed on the side wall of the sliding plate 342. The bottom end of the connecting plate 343 is located below the push-pull plate 344, and the bottom surface of the connecting plate 343 is fixed on the top surface of the base 345. The telescopic cylinder 341 drives the push-pull plate 344 to move, so that the push-pull plate 344 drives the sliding plate 342 to move along the guide rail 3411, and then drives the connecting plate 343 and the base 345 to move. By providing the sliding plate 342, the stability of the lifting ring heat sealing head 34 during use is improved, and the telescopic rod of the telescopic cylinder 341 is also prevented from being bent and deformed.

[0046] Further, referring to Figure 2 and Figure 6 As shown in the figure, in a specific embodiment of the present application, a stop plate 321 is fixed on the surface of the work platform 32, the stop plate 321 is made of stainless steel, and the position of the stop plate 321 corresponds to the position of the hanging ring 6 to be heat-sealed on the PE film and is located below the PE film. The stop plate 321 abuts against the heating head 346, which on the one hand reduces the damage caused by the collision and extrusion of the heating head 346 on the surface of the work platform 32, and on the other hand, the mutual clamping between the heating head 346 and the stop plate 321 enables the heating head 346 to better extrude and heat-seal the hanging ring 6 to the PE film, thereby improving the stability of the heat-sealing of the hanging ring 6. In addition, a horizontal pressure rod 35 is also arranged on the work platform 2, the pressure rod 35 is located above the PE film, the two ends of the pressure rod 35 are fixed on the fixed blocks 37 on the rack 31, and a pressure roller 351 for pressing the PE film is fixed on the pressure rod 35, the position of the pressure roller 351 corresponds to the position of the stop plate 321, so that the PE film passes through the pressure roller 351 and the stop plate 321 in turn. The pressure roller 351 is used to press the PE film, so that the PE film is in a tension state when passing through the stop plate 321, thereby avoiding wrinkles on the PE film and enabling the hanging ring 6 to be better heat-sealed to the PE film.

[0047] Working process and principle of the present application:

[0048] In use, the PE film passes through the pressure roller 351 and the stop plate 321 in turn, the pressure roller 351 is used to press the PE film, the equipment is started, and the PE film is moved and discharged under the driving of the traction device 5. At this time, the hanging ring heat-sealing device 3 is started to take and heat-seal the hanging ring 6. The hanging ring heat-sealing head 34 moves horizontally under the driving of the electric sliding rail 33 and moves above the hanging ring placing rack 36. At this time, the telescopic cylinder 341 is started, the telescopic rod is extended, and the heating head 346 is vertically moved downward. When the heating head 346 contacts the hanging ring 6 stacked on the placing platform 363, the air pump 38 is started and is in a suction operation state, so that the suction pipe 347 sucks the uppermost hanging ring 6. Then, the telescopic rod of the telescopic cylinder 341 is retracted to lift the hanging ring 6, and the hanging ring heat-sealing head 34 is moved again by the electric sliding rail 33 and is located directly above the stop plate 321. At this time, the telescopic rod of the telescopic cylinder 341 is extended to vertically lower the heating head 346 and the hanging ring 6 together and make them contact the PE film. The heating head 346 presses the hanging ring 6 on the PE film. When the hanging ring 6 contacts the PE film, the motor heating element 349 is started to heat and warm the heating head 346, and the film 601 on the hanging ring 6 is heat-sealed to the PE film. Then, the air pump 38 is started and is in an exhaust operation state, so that the air pressure in the suction pipe 347 is consistent with the external air pressure, thereby making the hanging ring 6 separate from the bottom end of the suction pipe 347. Finally, the telescopic rod of the telescopic cylinder 341 is retracted to make the heating head 346 away from the PE film, and the next cycle process is performed.
