Description

Technical Field

[0001] The utility model relates to the technical field of film rolling devices, in particular to a packaging film rolling device. Background Art

[0002] Packaging film is a thin film material commonly used to protect and encapsulate products. Depending on the application and material, packaging film can be divided into plastic film, aluminum foil film, and composite film. Plastic film is the most common type of packaging film and is often used for packaging food and goods.

[0003] Patent publication number CN117485960A, published on February 2, 2024, discloses a packaging film winding device comprising a frame, a rotating frame, and a support rod assembly. The rotating frame comprises a rotating shaft rotatably mounted on the frame. Three brackets are arranged in a circumferential array at each end of the rotating shaft, and the brackets at each end of the rotating shaft are arranged in pairs. Six support assemblies are mounted on the brackets. The support assemblies include a sleeve extending through the bracket, with its axis parallel to the rotating shaft and movable along the axis. A conical sleeve is externally mounted on the sleeve, located between the two paired brackets, with the apex of the sleeve facing between the two brackets. The conical sleeve is connected to the front end of the sleeve by a tension spring. A support rod is coaxially extending through the sleeve, movable along the axis. The rear end of the support rod is located outside the bracket, and a retaining ring and a driven wheel are sequentially disposed outward from the rear end of the support rod.

[0004] Including the above-mentioned patents, in the current production of packaging film, the packaging film is wound into a roll to form multiple independent units for subsequent further processing and use. After the packaging film is wound into a roll, it is usually cut. Cutting generally includes manual cutting and machine cutting. The manual cutting method is cumbersome and time-consuming and labor-intensive. When cutting by machine, the plastic film is clamped and then cut by moving the cutter. Machine cutting is not only fast but also smooth. However, some existing equipment adopts a fixed-point cutting method, that is, cutting on one side of the roll film. Then, the cut film still needs to be picked up manually and wound on a new film winding roller. In this process, the cut plastic film lacks certain support and is prone to large-scale deviation, thereby affecting the flatness of the subsequent roll film. In addition, the cut and falling plastic film is prone to folding and needs to be manually folded to make it flat. This process is cumbersome and affects the overall roll film process.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-6 As shown, a packaging film rolling device includes a winding platform 1 and a winding roller 5 rotating on the winding platform 1, a swing rod 2 provided on the winding platform 1, and a cutting positioning assembly provided on the swing rod 2. The cutting positioning assembly includes:

[0028] The support platform 21 is fixedly mounted on the swing rod 2 and arranged parallel to the main packaging film 4 wound around the outer wall of the winding roller 5;

[0029] A cutting blade 28 is located on one side of the support platform 21 and slides along the support platform 21;

[0030] The suction box 3 is symmetrically arranged at the bottom of the support platform 21, and the suction port 33 of the centrifugal fan 31 installed in the suction box 3 is movably arranged on the primary packaging film 4. By placing the suction box 3 on the support platform 21 close to the primary packaging film 4, and then when the primary packaging film 4 needs to be cut, the centrifugal fan 31 is started to suck the primary packaging film 4 through the suction port 33, and then the cutting knife 28 is slid along the direction of the support platform 21 to complete the cutting of the primary packaging film 4. At this time, the centrifugal fan 31 continues to suck the primary packaging film 4 to prevent the primary packaging film 4 from detaching from the suction box 3, thereby facilitating the subsequent workers to stretch the primary packaging film 4 to continue the film winding operation.

[0031] Specifically, a film winding motor 51 is fixedly installed on the winding table 1, and one end of the winding roller 5 is fixedly installed on the output end of the film winding motor 51. The film winding motor 51 drives the winding roller 5 to rotate to realize the operation of winding the main packaging film 4.

[0032] As a technical solution further provided by the present invention, the swing rod 2 is rotatably arranged on the winding platform 1, and the swing rod 2 is flipped to drive the suction box 3 to be located on one side of the winding roller 5.

[0033] Specifically, such as Figure 1 and Figure 4 As shown, a swing motor 24 is fixedly mounted on the winding table 1, and the first end of the swing arm 2 is fixedly mounted on the output end of the swing motor 24, while the second end of the swing arm 2 is fixedly mounted on the support table 21. The exhaust port 32 on the centrifugal fan 31 faces the outside of the suction box 3. The centrifugal fan 31 is started to suck the main packaging film 4 through the exhaust port 33, and then the cutting knife 28 is slid along the support table 21 to complete the cutting of the main packaging film 4. At this time, the centrifugal fan 31 continues to absorb the main packaging film 4 to prevent the main packaging film 4 from detaching from the suction box 3. The swing motor 24 then drives the swing arm 2 to flip and swing, thereby causing the suction box 3 to flip toward the winding roller 5. At the same time, due to the suction of the main packaging film 4 by the exhaust port 33, the end of the cut main packaging film 4 is driven to flip toward the winding roller 5, eliminating the manual stretching operation and speeding up the production process.

[0034] Furthermore, a screw rod 25 is rotatably provided on a side platform 22 fixedly installed on one side of the support platform 21 , and a slider 27 slidably provided on the side platform 22 is threadedly rotatably provided on the screw rod 25 , and a cutting knife 28 is fixedly installed on the slider 27 .

[0035] Specifically, a cutting motor 26 is fixedly installed on the side platform 22, and one end of the screw rod 25 is fixedly installed on the output end of the cutting motor 26. The cutting motor 26 is then used to drive the screw rod 25 to rotate, so that the slider 27 is threadedly rotated on the screw rod 25 and drives the cutting knife 28 to cut the main packaging film 4.

[0036] Furthermore, the suction boxes 3 slide symmetrically on the bottom of the support platform 21 , and the two suction boxes 3 keep moving in opposite directions to move toward the two sides of the main packaging film 4 respectively.

[0037] Specifically, by keeping the two suction boxes 3 moving in opposite directions to move toward the two side edges of the main packaging film 4 respectively, when the main packaging film 4 is cut, the two suction boxes 3 keep moving in opposite directions synchronously, thereby driving the main packaging film 4 to be flattened to a certain extent on both sides, so as to smooth out the wrinkles that appear when the cutting knife 28 cuts the main packaging film 4, so as to facilitate the subsequent smooth film winding operation.

[0038] Furthermore, a protrusion 11 is fixedly mounted on the winding platform 1 , and the inclined surfaces 12 symmetrically arranged on the protrusion 11 are respectively located on the flipping path of the paddle 34 fixedly mounted on the suction box 3 .

[0039] The suction box 3 is fixedly provided with a spring member 35, and the first end of the spring member 35 is fixedly installed on the support platform 21. When the cutting knife 28 slides along the direction of the support platform 21 to complete the cutting of the main packaging film 4, the main packaging film 4 is continuously adsorbed by the centrifugal fan 31, and then the swing motor 24 drives the swing arm 2 to flip and swing, so that the suction box 3 is flipped toward the side of the winding roller 5. At the same time, due to the adsorption of the main packaging film 4 by the exhaust port 33, the end of the cut main packaging film 4 is driven to flip toward the side of the winding roller 5. As the swing arm 2 flips and swings, the two paddles 34 are driven to press against the inclined surfaces 12 symmetrically arranged on the protrusion 11. At this time, the two suction boxes 3 are pushed to move toward the two sides of the main packaging film 4 respectively, thereby cooperating with the adsorption of the main packaging film 4 by the exhaust port 33 to perform a certain leveling operation on the main packaging film 4. At the same time, when the suction box 3 slides, the spring member 35 is deformed and stored, and then the spring member 35 releases the stored force when the paddle 34 is separated from the protrusion 11.

[0040] Furthermore, the pressing plate 23 fixedly installed at the bottom of the side platform 22 is movably arranged on the main packaging film 4 .

[0041] Specifically, the swing rod 2 is turned toward the main packaging film 4 so that the pressing plate 23 is pressed on the main packaging film 4 , thereby tightening the main packaging film 4 to facilitate cutting by the cutting knife 28 .

[0042] Furthermore, the dial plate 34 is a stainless steel plate.

[0043] Working principle: The film winding motor 51 is used to drive the winding roller 5 to rotate to realize the operation of winding the main packaging film 4. When the main packaging film 4 needs to be cut, the swing motor 24 is used to drive the swing rod 2 to flip and swing so that the pressure plate 23 is pressed on the main packaging film 4. At the same time, the centrifugal fan 31 is started to make the exhaust port 33 continuously adsorb the main packaging film 4, and then the cutting motor 26 drives the screw rod 25 to rotate, so that the slider 27 is threadedly rotated on the screw rod 25, and drives the cutting knife 28 to cut the main packaging film 4. When the cutting knife 28 slides along the direction of the support platform 21 to complete the cutting of the main packaging film 4, the main packaging film 4 is continuously adsorbed by the centrifugal fan 31, and then the swing motor 24 drives the swing arm 2 to flip and swing, so that the suction box 3 flips toward the side of the winding roller 5. At the same time, due to the adsorption of the main packaging film 4 by the exhaust port 33, the end of the cut main packaging film 4 is driven to flip toward the side of the winding roller 5. As the swing arm 2 flips and swings, the two paddles 34 are driven to be squeezed on the inclined surfaces 12 symmetrically arranged on the protrusion 11. At this time, the two suction boxes 3 are squeezed to move to the two sides of the main packaging film 4 respectively, thereby cooperating with the adsorption of the main packaging film 4 by the exhaust port 33 to perform a certain leveling operation on the main packaging film 4.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
