Description

Technical Field

[0001] This utility model relates to the field of film winding machine technology, and in particular to an automatic film winding machine. Background Technology

[0002] Automatic film winding machines are mechanical devices used for automated processing of roll film materials. They enable automatic film winding, using a motor-driven film winding shaft to rotate, allowing the film material to be smoothly and continuously unwound or wound. Combined with cutting, welding, and labeling devices, they complete processes such as fixed-length cutting, heat sealing, and label application of the roll film. Widely used in food packaging, agricultural covering, and industrial material processing, they significantly improve production efficiency, reduce labor costs, and ensure the processing accuracy and quality stability of roll film products.

[0003] However, in existing film winding machines, impurities tend to accumulate on the guide rollers during the winding process, affecting the quality of the packaging film. Simultaneously, wrinkles and air bubbles easily appear on the packaging film during winding, and dust and impurities adhere to the film surface, impacting the winding effect and product quality. These drawbacks exist in their use.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides an automatic film winding machine, which can prevent impurities on the surface of the guide roller from affecting the packaging film body. At the same time, during the winding process, it can repeatedly tap the bottom of the packaging film body to make the winding smoother, reduce wrinkles and air bubbles, and ensure the winding quality.

[0006] The technical solution adopted by this utility model is as follows: it includes a mounting base and a packaging film body. The mounting base is fixedly mounted with a winding seat and a guide seat. The winding seat is rotatably mounted with a winding roller for winding the packaging film body. The guide seat is rotatably mounted with a supporting guide roller and a cleaning brush roller. The cleaning brush roller is located on one side of the bottom of the supporting guide roller, and the bristles on the cleaning brush roller are in contact with the outer wall of the supporting guide roller. The cleaning brush roller is connected to the winding roller through a synchronous drive assembly. The mounting base is fixedly mounted with a reciprocating striking assembly. The reciprocating striking assembly is located below the packaging film body and is used to reciprocate striking the packaging film body. One end of the reciprocating striking assembly is connected to the cleaning brush roller.

[0007] Preferably, in order to enable the drive shaft to drive the take-up roller to rotate on the take-up seat by controlling the drive motor to start, the synchronous drive assembly includes the L-shaped mounting base and the synchronous wheel. The L-shaped mounting base is fixed on the outer wall of the take-up seat, and the drive motor is fixedly mounted on the L-shaped mounting base. The take-up roller is fixedly connected to the output shaft of the drive motor through the drive shaft.

[0008] Preferably, in order for the drive shaft to drive the cleaning brush roller to rotate when the first timing belt is used, the timing wheel is fixed to one end of the cleaning brush roller, and the timing wheel is connected to the drive shaft through the first timing belt.

[0009] Preferably, in order to enable the cleaning brush roller to rotate via the driven rotating shaft when the second synchronous belt rotates, the reciprocating striking assembly includes the vertical mounting plate, which is fixed to the top of the mounting base. The driven rotating shaft is rotatably mounted on the vertical mounting plate. The driven rotating shaft is connected to the cleaning brush roller via the second synchronous belt, and the driven rotating shaft is fixedly sleeved on the driven rotating shaft.

[0010] Preferably, in order to allow the lifting slider to slide up and down in the limiting through-hole groove via the vertical limiting slide rod, a limiting through-hole groove is provided on the top side of the vertical mounting plate, the vertical limiting slide rod is fixedly installed on the inner wall of the limiting through-hole groove, the lifting slider is slidably sleeved on the vertical limiting slide rod, and the lifting slider is slidably engaged in the limiting through-hole groove.

[0011] Preferably, in order for the lifting slider to be reset in the limiting through-hole groove by means of the reset spring, the lifting slider is elastically connected to the inner wall of the top end of the limiting through-hole groove by means of the reset spring.

[0012] Preferably, in order to enable the packaging film body to be struck by controlling the lifting and lowering of the striking head, the striking head is fixedly installed on the lifting slider, and the striking head is located below the packaging film body.

[0013] Preferably, in order to reciprocate and press the striking head by controlling the rotation of the push cam, the bottom of the striking head is in close contact with the push cam, and the top of the striking head is smooth and in close contact with the bottom of the packaging film body.

[0014] The beneficial effects of this invention are as follows: During winding, the synchronous drive component rotates the cleaning brush roller, whose bristles clean and lift impurities from the guide roller surface, preventing them from affecting the packaging film itself. Simultaneously, the rotation of the cleaning brush roller drives the reciprocating striking component to reciprocate and strike the underside of the packaging film, resulting in a smoother winding, reduced wrinkles and air bubbles, ensuring winding quality, and removing adhering dust and impurities. Overall, this improves the function and effectiveness of the film winding machine. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-5As shown, this embodiment provides an automatic film winding machine, including a mounting base 1 and a packaging film body 2. A winding seat 3 and a guide seat 4 are fixedly mounted on the top of the mounting base 1. A winding roller 5 for winding the packaging film body 2 is rotatably mounted on the winding seat 3. A supporting guide roller 6 and a cleaning brush roller 7 are rotatably mounted on the guide seat 4. The cleaning brush roller 7 is located on one side of the bottom of the supporting guide roller 6, and the bristles on the cleaning brush roller 7 are in contact with the outer wall of the supporting guide roller 6. The cleaning brush roller 7 is connected to the winding roller 5 via a synchronous drive assembly 8. A reciprocating striking assembly 9 is fixedly mounted on the top of the mounting base 1. The reciprocating striking assembly 9 is located below the packaging film body 2 and is used to reciprocate striking the packaging film body 2. One end of the reciprocating striking assembly 9 is connected to the cleaning brush roller 7. In use, one end of the packaging film body 2 is fixed to the winding roller 5. The synchronous drive assembly 8 is activated, and the winding roller 5 rotates to begin winding the packaging film body 2. During the winding process, the synchronous drive component 8 drives the cleaning brush roller 7 to rotate. Its bristles contact the outer wall of the support guide roller 6, cleaning impurities from the surface of the support guide roller 6 and preventing damage to the packaging film body 2. At the same time, the rotation of the cleaning brush roller 7 also drives the reciprocating striking component 9 to operate. The reciprocating striking component 9 is located below the packaging film body 2 and reciprocates striking the packaging film body 2, making the packaging film body 2 flatter during winding, reducing wrinkles and bubbles, ensuring winding quality, and knocking off dust and impurities adhering to the packaging film body 2.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 3 As shown, the synchronous drive assembly 8 includes an L-shaped mounting base 801 and a synchronous pulley 802. The L-shaped mounting base 801 is fixed on the outer wall of the take-up base 3. A drive motor 803 is fixedly mounted on the L-shaped mounting base 801. The take-up roller 5 is fixedly connected to the output shaft of the drive motor 803 via a drive shaft 804. The synchronous pulley 802 is fixed to one end of the cleaning brush roller 7 and is connected to the drive shaft 804 via a first synchronous belt 805. In use, the drive motor 803 fixedly mounted on the L-shaped mounting base 801 is started. The output shaft of the drive motor 803 drives the drive shaft 804 to rotate, thereby driving the take-up roller 5 to rotate and take up the packaging film body 2. At the same time, the drive shaft 804 drives the synchronous pulley 802 at one end of the cleaning brush roller 7 to rotate via the first synchronous belt 805, causing the cleaning brush roller 7 to rotate accordingly, completing the cleaning work on the support guide roller 6.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 4 and Figure 5As shown, the reciprocating striking assembly 9 includes a vertical mounting plate 901, which is fixed to the top of the mounting base 1. A driven rotating shaft 902 is rotatably mounted on the vertical mounting plate 901. The driven rotating shaft 902 is connected to the cleaning brush roller 7 via a second synchronous belt 903. A push cam 904 is fixedly sleeved on the driven rotating shaft 902. A limit through hole groove is opened on the top side of the vertical mounting plate 901. A vertical limit slide rod 905 is fixedly mounted on the inner wall of the limit through hole groove. A lifting slider 906 is slidably sleeved on the vertical limit slide rod 905. The lifting slider 906 is slidably engaged with the limit slide rod 905. In the through-hole groove, the lifting slider 906 is elastically connected to the inner wall of the top of the limiting through-hole groove via a return spring 907. A striking head 908 is fixedly installed on the lifting slider 906. The striking head 908 is located below the packaging film body 2. The bottom of the striking head 908 is in contact with the push cam 904, and the top of the striking head 908 is smooth and in contact with the bottom of the packaging film body 2. In use, the synchronous drive assembly 8 is activated to rotate the cleaning brush roller 7. The cleaning brush roller 7 drives the driven rotating shaft 902 to rotate via the second synchronous belt 903, which in turn drives the push cam 904 on it to rotate. When the push cam 904 rotates, it periodically pushes the lifting slider 906 to slide along the vertical limiting slide bar 905. Under the action of the return spring 907, the lifting slider 906 drives the striking head 908 to move up and down reciprocally, continuously striking the bottom of the packaging film body 2, so that the packaging film body 2 remains flat during the winding process, reducing wrinkles and ensuring winding quality.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope.
