A guide rod 4 is slidably inserted into the bottom end of the fixed frame 3, and the top end of the guide rod 4 passes through the fixed frame 3 and corresponds to the lifting column 2. A pressing top circular plate 5 is fixedly connected to the bottom end of the guide rod 4. An installation bottom plate 13 is slidably connected to the bottom end of the fixed frame 3. A film clamping and cutting assembly 6 is arranged at the bottom end of the installation bottom plate 13. A lifting assembly is arranged between the lifting column 2 and the fixed base 1, and the lifting assembly is used to control the lifting of the lifting column 2 inside the fixed base 1. A transverse movement assembly is arranged between the fixed frame 3 and the installation bottom plate 13, and the transverse movement assembly is used to control the sliding of the installation bottom plate 13 and the film clamping and cutting assembly 6 on the fixed frame 3.

[0031] In this embodiment, the fixed base 1 is installed on the film winding machine. When the film winding machine packs a product, the lifting assembly controls the lifting column 2 to move downward. The lifting column 2 drives the fixed frame 3 to move downward, so that the pressing top circular plate 5 presses on the top of the product. The guide rod 4 stabilizes products of different heights through telescoping at the bottom end of the lifting column 2, preventing the products from falling when being wound with the film. At the same time, the film clamping and cutting assembly 6 corresponds to one side of the upper part of the product. The film clamping and cutting assembly 6 clamps one end of the film, moves to correspond to the product through the transverse movement assembly. The film winding machine winds the film around the product for packaging. After the product packaging is completed, the film clamping and cutting assembly 6 heats and cuts the film. The transverse movement assembly controls the movement of the film clamping and cutting assembly 6 through the mounting base plate 13, so that one end of the heated and cut film is pasted on the product, thereby preventing it from falling. Finally, the lifting assembly controls the lifting column 2 to reset, and the film clamping and cutting assembly 6 folds under the fixed frame 3. Among them, when the film clamping and cutting assembly 6 folds, it will clamp one end of the unused film, which is convenient for winding the film for subsequent products.

[0032] Specifically, the film clamping and cutting assembly 6 includes a connecting rod component 61. The connecting rod component 61 is movably hinged to the bottom end of the mounting base plate 13 through a hinge shaft. A film clamping bottom plate 62, a film clamping plate 63, a film burning block 66 and a film burning electric heating sheet 67 are movably hinged to the connecting rod component 61 through hinge shafts. The film clamping bottom plate 62 and the film clamping plate 63 correspond to each other, and the film burning block 66 and the film burning electric heating sheet 67 correspond to each other. A film clamping cylinder 64 is movably hinged to the film clamping bottom plate 62 through a hinge shaft, and the output end of the film clamping cylinder 64 is movably hinged to the connecting rod component 61 through a hinge shaft.

[0033] In this embodiment, the film clamping cylinder 64 controls the connecting rod component 61 to fold the film clamping plate 63. The film clamping plate 63 cooperates with the film clamping bottom plate 62 to clamp and fix the film. The film burning plate turning cylinder 610 controls the film burning block 66 to unfold through the connecting rod component 61. After unfolding, the film burning block 66 corresponds to the film burning electric heating sheet 67. The film burning pressing cylinder 69 controls the film burning electric heating sheet 67 to move closer to the film burning block 66, thereby clamping and heating the film. At the same time, the film cutting electric wire 68 moves with the film burning electric heating sheet 67 to thermally cut the film, realizing film cutting. After the film clamping and cutting are completed, the film clamping turning cylinder 65 expands and contracts to control the film clamping bottom plate 62, the film clamping plate 63, the film clamping cylinder 64 and the film burning electric heating sheet 67 to fold through the connecting rod component 61, and the film burning plate turning cylinder 610 expands and contracts to control the film burning block 66 to fold through the connecting rod component 61.

[0034] Specifically, the lifting assembly includes a lifting motor 71, which is fixedly connected to the fixed base 1. The output end of the lifting motor 71 is fixedly connected with a lifting gear 72. A lifting rack 73 is fixedly connected to the lifting column 2, and the lifting rack 73 meshes with the lifting gear 72.

[0035] In this embodiment, the lifting motor 71 is started by an external power source to control the rotation of the lifting gear 72. The lifting gear 72 makes the lifting column 2 move in the up and down directions through the meshing connection with the lifting rack 73, realizing the control of the lifting column 2.

[0036] Specifically, the transverse movement assembly includes a rodless cylinder 81, which is fixedly connected inside the fixed frame 3. An external load block 82 is slidably connected to the rodless cylinder 81. The bottom end of the external load block 82 is fixedly connected with a sliding seat 83, and the mounting base plate 13 is fixedly connected to the bottom end of the sliding seat 83.

[0037] In this embodiment, the rodless cylinder 81 controls the external load block 82 to slide inside the fixed frame 3. The external load block 82 drives the sliding seat 83 to make the mounting base plate 13 slide at the bottom end of the fixed frame 3, realizing the control of the moving direction of the film clamping and cutting assembly 6.

[0038] Specifically, a lifting guide rail 9 is arranged between the fixed base 1 and the lifting column 2, and a transverse movement guide rail 10 is arranged between the sliding seat 83 and the fixed frame 3.

[0039] In this embodiment, the lifting column 2 can stably slide inside the fixed base 1 through the lifting guide rail 9, ensuring the stability of the lifting column 2 during sliding. The mounting base plate 13 and the film clamping and cutting assembly 6 can stably move by sliding at the bottom end of the fixed frame 3 through the transverse movement guide rail 10.

[0040] Specifically, a linear bearing 11 is fixedly connected to the bottom end of the fixed frame 3, and the guide rod 4 is slidably connected inside the linear bearing 11. A counterweight block 12 is fixedly connected to the top end of the pressing circular plate 5.

[0041] In this embodiment, the linear bearing 11 makes the sliding and telescoping of the guide rod 4 smoother. The counterweight block 12 increases the weight of the pressing circular plate 5, enabling the pressing circular plate 5 to stably press the product and prevent the product from loosening and falling during winding.

[0042] Working principle: The fixed base 1 is installed on the film winding machine. When the film winding machine packs products, the lifting motor 71 controls the rotation of the lifting gear 72. The lifting gear 72 drives the lifting column 2 to move downward through the meshing connection with the lifting rack 73. The lifting column 2 drives the fixed frame 3 to move downward, so that the pressing top circular plate 5 presses on the top of the product. The pressing top circular plate 5 stabilizes products of different heights through the telescopic movement of the guide rod 4 at the bottom end of the lifting column 2. At the same time, the film clamping and cutting assembly 6 corresponds to the upper side of one side of the product. The film clamping cylinder 64 controls the folding of the film clamping plate 63 through the control link component 61. The film clamping plate 63 cooperates with the film clamping bottom plate 62 to clamp and fix the film. The rodless cylinder 81 controls the outer load block 82 to slide in the fixed frame 3. The outer load block 82 drives the sliding seat 83 to make the mounting bottom plate 13 and the film clamping and cutting assembly 6 slide on the lower side of the fixed frame 3. The film clamping and cutting assembly 6 moves one end of the clamped film to correspond to the product. The film winding machine winds and packs the film around the product. After the product packing is completed, the film burning plate flipping cylinder 610 controls the unfolding of the film burning block 66 through the link component 61. The unfolded film burning block 66 corresponds to the film burning electric heating sheet 67. The film burning pressing cylinder 69 controls the film burning electric heating sheet 67 to move closer to the film burning block 66, so as to clamp and heat the film. At the same time, the film cutting electric wire 68 moves with the film burning electric heating sheet 67 to thermally cut the film, realizing film cutting. After the film clamping and cutting are completed, the rodless cylinder 81 controls the movement of the outer load block 82, so that the sliding seat 83 drives the mounting bottom plate 13 and the film clamping and cutting assembly 6 to move towards the product, making one end of the heated and cut film stick to the product, thus preventing it from falling. Finally, the lifting motor 71 rotates in the reverse direction, and the lifting column 2 is reset through the lifting gear 72 and the lifting rack 73. The telescopic movement of the film clamping flipping cylinder 65 controls the folding of the film clamping bottom plate 62, the film clamping plate 63, the film clamping cylinder 64 and the film burning electric heating sheet 67 through the link component 61. The telescopic movement of the film burning plate flipping cylinder 610 controls the folding of the film burning block 66 through the link component 61. The film clamping and cutting assembly 6 clamps one end of the unused film and folds it under the fixed frame 3, which is convenient for film winding of subsequent products.
