Technical Field

[0001] This utility model relates to the field of cargo packaging technology, specifically to an automatic film cutting and wrapping machine. Background Technology

[0002] Automatic film cutting and wrapping machines are automated packaging equipment, mainly divided into two types: cargo rotation type and film carriage rotation type. Due to their advantages such as ease of use, reliability, and ease of operation, automatic film cutting and wrapping machines are widely used in industries such as food and daily chemicals, chemical building materials, and electronic precision instruments.

[0003] However, existing automatic film cutting and wrapping machines have the following problems when in use:

[0004] Because the height of goods varies, the device needs to be able to easily adjust the height of the film holder so that the device can wrap the film around different positions of the goods. However, the existing automatic film cutting and wrapping machine is not convenient to adjust the height of the film holder, which makes it difficult for the device to wrap the film around different positions of the goods, thus reducing the practicality of the device.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing automatic film cutting and wrapping machine. Utility Model Content

[0006] The purpose of this invention is to provide an automatic film cutting and wrapping machine to solve the problem mentioned in the background art that the existing automatic film cutting and wrapping machines are inconvenient to adjust the height of the film frame, making it difficult for the device to wrap the film at different positions of the goods, thus reducing the practicality of the device.

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an automatic film cutting and wrapping machine, including a base plate 1, a bracket 2, a support ring 3, a main motor 4, a support mechanism 5, a tray 501, rollers 502, a transmission rod 503, a pulley mechanism 6, a secondary sprocket 7, a servo motor 8, a main sprocket 9, a chain 10, a positioning plate 11, a transmission seat 12, a film frame 13, a positioning frame 14, an electric telescopic rod 15, and a film cutter 16. The bracket 2 and the support ring 3 are fixed to both ends of the upper surface of the base plate 1, and the main motor 4 is installed at the lower end of the outer wall of the side of the bracket 2. The support mechanism 5 is provided on the inner wall of the support ring 3. A secondary sprocket 7 is installed on the upper inner wall, and a servo motor 8 is installed at the lower end of the back of the bracket 2. The output shaft of the servo motor 8 is fixedly connected to the main sprocket 9. Both the secondary sprocket 7 and the main sprocket 9 are equipped with chains 10. A positioning plate 11 is fixedly installed on the upper surface of the bottom plate 1 on the side of the bracket 2. A transmission seat 12 is sleeved on the outer wall of the positioning plate 11. A film frame 13 is installed on the side of the transmission seat 12. A positioning frame 14 is fixedly connected to the upper surface of the film frame 13. An electric telescopic rod 15 is installed on the positioning frame 14. A film cutter 16 is fixedly connected to the lower end of the output shaft of the electric telescopic rod 15.

[0025] The support mechanism 5 includes a pallet 501, rollers 502 and a transmission rod 503. The pallet 501 is movably mounted on the inner wall of the support ring 3. The rollers 502 are provided at the lower edge of the pallet 501. The transmission rod 503 is fixedly connected to the center of the lower surface of the pallet 501, so that the goods can be rotated through the support mechanism 5, and the film can be wrapped around the surface of the goods.

[0026] The tray 501 and the support ring 3 form a rotating structure, which facilitates the stable rotation of the tray 501 relative to the support ring 3.

[0027] The roller 502 is in contact with the base plate 1, so that when the pallet 501 rotates, the pallet 501 drives the roller 502 to move relative to the base plate 1, thereby improving the stability of the rotation of the pallet 501.

[0028] The lower outer wall of the transmission rod 503 is connected to the outer wall of the output shaft of the main motor 4 through the pulley mechanism 6, so that the main motor 4 can drive the transmission rod 503 to rotate through the pulley mechanism 6, thereby causing the transmission rod 503 to drive the tray 501 to rotate.

[0029] The secondary sprocket 7 and the output shaft of the servo motor 8 are both rotatably connected to the bracket 2, so that when the servo motor 8 drives the main sprocket 9 to rotate, the main sprocket 9 drives the chain 10, which in turn drives the secondary sprocket 7 to rotate, thereby making the chain 10 move stably.

[0030] One end of the chain 10 is fixedly connected to the upper surface of the transmission seat 12, and the other end of the chain 10 is fixedly set to the lower surface of the transmission seat 12, so as to facilitate the movement of the chain 10 and drive the transmission seat 12 to move vertically.

[0031] The transmission seat 12 and the positioning plate 11 form a sliding structure, which facilitates the sliding of the transmission seat 12 relative to the positioning plate 11, so that the transmission seat 12 moves stably, thereby driving the film frame 13 to move stably for height adjustment.

[0032] Working principle: When using this automatic film cutting and wrapping machine, firstly as follows... Figure 1-5 As shown, the user places the goods to be wrapped with film on the pallet 501. Then, the user attaches the end of the film on the film holder 13 to the goods. Next, the user starts the main motor 4, which drives the transmission rod 503 to rotate via the pulley mechanism 6. The transmission rod 503 then drives the pallet 501 to rotate relative to the support ring 3. Simultaneously, the pallet 501 drives the roller 502 to move relative to the base plate 1, causing the pallet 501 to rotate the goods. During this process, the film continuously wraps around the outside of the goods. When processing is required at different locations on the goods, the user starts the servo motor 8, which then drives the main sprocket 9 to rotate. The main sprocket 9 then drives the chain 10 to move, while the chain 10 drives the secondary chain... Wheel 7 rotates relative to bracket 2, then chain 10 drives transmission seat 12 to move vertically relative to positioning plate 11. Next, transmission seat 12 drives film holder 13 to move vertically relative to goods, so that the film is wrapped around different positions of the goods. After the film is wrapped, the user turns off main motor 4 and servo motor 8, then the user starts electric telescopic rod 15. The electric telescopic rod 15 then drives film cutter 16 to move down, so that film cutter 16 cuts the film, thus completing the automatic wrapping and cutting of the film. At the same time, the device is convenient to wrap the film around different positions of the goods, so the height of film holder 13 can be easily adjusted, thus facilitating the wrapping of the film around different positions of the goods and improving the practicality of the device.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
