Detailed Implementation

[0022] 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.

[0023] Example 1:

[0024] This embodiment is used to solve the problem that it is difficult to automatically smooth out the protruding parts of the corners of rectangular boxes, thus making it difficult to ensure the neatness and smoothness of the packaging box edges.

[0025] Please see Figures 1-5 As shown, this embodiment is a device for automatic film clamping in a packaging machine, including an operating table 1. The cross-section of the operating table 1 is an inverted U-shape. Two symmetrically arranged mounting seats 4 are fixedly connected to the upper surface of the operating table 1. A connecting frame 5 is horizontally slidably connected to the mounting seat 4. The connecting frame 5 slides on the mounting seat 4. An electric push rod 6 is fixedly connected to the opposite side of the two connecting frames 5. A hot press plate 7 is fixedly connected to the telescopic end of the electric push rod 6. The position of the hot press plate 7 is not limited to the fixed style shown in the figure and the text description, and can also be replaced on the support plate 3.

[0026] Two electric push rods 6 are installed on opposite sides of two connecting frames 5 via a frame. Two sliding rods are vertically slidably connected on the frame to limit the vertical movement of the hot press plate 7. A support plate 3 corresponding to the hot press plate 7 is fixedly connected to the inner wall of the support plate 3. The telescopic end of the electric push rod 6 pushes the hot press plate 7 to move vertically and contact the support plate 3, thereby hot-pressing and cutting off the excess material on the corners of the packaging box. A smoothing mechanism is fixedly connected to the upper surface of the operating table 1.

[0027] The smoothing mechanism includes a fixed seat 8 fixedly connected to the upper surface of the workbench 1. The surface of the fixed seat 8 is provided with a groove. Two symmetrically arranged sliding blocks 9 are slidably connected to the inner wall of the groove of the fixed seat 8. A screw 17 is rotatably connected to the inner wall of the groove of the fixed seat 8. The screw 17 passes through the sliding block 9 and is screwed to the sliding block 9. The two sliding blocks 9 are provided with opposite thread structures. A connecting plate 10 is fixedly connected to the surface of the sliding block 9. A smoothing strip 18 that contacts the outer packaging of the packaging box is fixedly connected to the lower surface of the connecting plate 10.

[0028] A motor is fixedly installed on one side of the outer wall of the fixed base 8. The motor drives the screw 17 to rotate, which enables the two sliding blocks 9 to move in the same or opposite directions. When the two sliding blocks 9 that are close to each other separate, the two smoothing strips 18 automatically push the protruding packaging film on the corner of the packaging box, so that the protruding packaging film bends to both sides, which makes it easier for the hot press plate 7 to move downward to hot press and cut the folded packaging film, thus making the packaging edge neat. The operating table 1 is vertically slidably connected to the lifting platform 2 for placing the packaging box. The lifting platform 2 moves in the vertical direction, which can adjust the vertical height of the packaging box, so that the packaging box can be kept flush with the support plate 3, which makes it easy for the hot press plate 7 and the support plate 3 to cooperate in hot cutting and remove the excess film from the edge of the packaging box.

[0029] A connecting seat 19 is fixedly connected to the upper surface of the mounting base 4. A screw 20 is rotatably connected to the connecting seat 19. The screw 20 passes through the connecting frame 5 and is screwed to the connecting frame 5. Two symmetrically arranged guide rails are fixedly connected to the upper surface of the mounting base 4. The guide rails on the mounting base 4 pass through the connecting frame 5 and are horizontally slidably connected to the connecting frame 5. The guide rails limit the horizontal movement of the connecting frame 5, so that the connecting frame 5 can move stably in the horizontal direction. Rotating the screw 20 allows the connecting frame 5 to move horizontally on the upper surface of the mounting base 4, thereby adjusting the horizontal position of the two hot press plates 7.

[0030] A horizontally set limiting strip 12 is fixedly connected to the inner wall of the operating table 1 near the upper surface. The limiting strip 12 passes through and is slidably connected to a sliding seat 11. The support plate 3 is fixedly connected to the surface of the sliding seat 11. The limiting strip 12 limits the horizontal direction of the sliding seat 11, thereby enabling the sliding seat 11 to move in the horizontal direction. It is suitable for film clamping operations on packaging boxes of different widths.

[0031] A fixing knob 13 is screwed onto the surface of the sliding seat 11. The fixing knob 13 passes through the sliding seat 11 and abuts against the limiting strip 12. By rotating the fixing knob 13, the position of the sliding seat 11 can be fixed or unfixed by moving the end of the fixing knob 13 closer to or away from the surface of the sliding seat 11, thereby adjusting the position of the sliding seat 11 and adjusting the position of the support plate 3 located on the sliding seat 11.

[0032] Example 2:

[0033] This embodiment is used to solve the problem of processing rectangular boxes of different heights.

[0034] Please see Figure 1 , Figure 5 As shown in the figure, in this embodiment, an automatic film clamping device for a packaging machine is provided. The inner wall of the operating table 1 is connected to a fixed plate 15 located on one side of the bottom of the lifting platform 2. Two symmetrically arranged limiting rods 16 are fixedly connected to the lower surface of the lifting platform 2. The two limiting rods 16 pass through the fixed plate 15 and are vertically slidably connected to the fixed plate 15. The two limiting rods 16 limit the vertical direction of the lifting platform 2, which can ensure that the lifting platform 2 can move stably in the vertical direction.

[0035] A screw 14 is rotatably connected to the lower surface of the lifting platform 2. The screw 14 passes through the fixing plate 15 and is screwed to the fixing plate 15. Rotating the screw 14 can adjust the vertical height of the lifting platform 2, thereby adjusting the height of the packaging box located on the lifting platform 2.

[0036] Combining Example 1 and Example 2

[0037] By setting up a smoothing mechanism, when the sliding blocks 9 approach each other, the two smoothing strips 18 can automatically push the protruding packaging film on the corners of the packaging box, causing it to bend to both sides, adapting to packaging boxes of different sizes and shapes, and effectively tidying up the corner film. This facilitates subsequent hot-press cutting operations, realizing automatic film clamping, hot-press cutting, and edge tidying of excess film on the corners of the packaging box, greatly improving packaging efficiency. At the same time, the device can adapt to packaging boxes of different heights, ensuring that the packaging box remains flush with the support plate 3, facilitating hot-press cutting operations. It has the advantages of high automation, high precision, strong adaptability, simple operation, improved packaging quality, and energy saving and environmental protection, bringing significant benefits and improvements to the packaging industry.

[0038] The working process and principle of this utility model are as follows:

[0039] Step 1: Adjust the device according to the dimensions of the packaging box. Rotating screw 14 adjusts the vertical height of the lifting platform 2, thereby adjusting the height of the packaging box on the lifting platform 2. Then, adjust the horizontal position of the sliding seat 11 so that the support plate 3 on the sliding seat 11 fits against the sides of the packaging box. Rotating screw 20 moves the connecting frame 5 horizontally on the upper surface of the mounting base 4, adjusting the horizontal position of the two hot press plates 7 so that their vertical positions correspond to the support plate 3.

[0040] Step 2: The motor drives the screw 17 to rotate, which enables the two sliding blocks 9 to move in the same or opposite directions. When the two sliding blocks 9 that are close to each other separate, the two smoothing strips 18 automatically push the protruding packaging film on the corner of the packaging box, thereby bending the protruding packaging film to both sides. The electric push rod 6 located on one side of the connecting frame 5 is activated. The telescopic end of the electric push rod 6 pushes the hot press plate 7 to move vertically and contact the support plate 3, thereby hot pressing and cutting off the excess on the corner of the packaging box.
