Description

Technical Field

[0001] This utility model relates to the field of film winding machine technology, specifically a film stretching and winding machine. Background Technology

[0002] The production of thin films involves first passing the melt of high molecular weight polypropylene through a narrow die head to form sheets or thick films, and then stretching them simultaneously or stepwise in two vertical directions (longitudinal and transverse) in a dedicated stretching machine at a certain temperature and set speed. The films are then produced by appropriate cooling or heat treatment or special processing (such as corona treatment, coating, etc.).

[0003] A search revealed a utility model patent in China with patent publication number CN214827661U, which discloses a BOPP film stretching and winding device. The device generally includes a first base and a second base, with a first support plate and a second support plate fixedly connected to the top of the first and second bases, respectively. In use, the stretched BOPP film is wound up using a BOPP film winding roller. After winding, the BOPP film winding roller needs to be replaced. This is done by loosening the fastening bolts, disassembling the fixing plate and mounting bracket, and then using a handle to directly connect the fixing plate, the second rotating shaft, and the first support plate. The two locking blocks separate from the second locking slot and the second rotating hole. Then, the right end of the BOPP film take-up roller that has been wound up is taken out from the first rotating shaft and the first locking block, thus completing the disassembly of the BOPP film take-up roller. This is convenient, quick, and saves time and effort. However, the above device still has some shortcomings. For example, when replacing the take-up roller, the above device cannot continue to wind up the film and the entire equipment must be stopped, which delays the efficiency of film winding production. In addition, when disassembling and replacing the above device, it is still necessary to use tools to remove multiple fastening bolts, which is a waste of time. Therefore, we propose a film stretching and winding machine. Utility Model Content

[0023] Example

[0024] Please see Figures 1-4 A film stretching and winding machine, comprising:

[0025] Support 1;

[0026] The winding mechanism is mounted on the support base 1 and includes two openings, each on the support base 1. A lifting plate 2 is slidably connected within each opening. Two electric cylinders 3 are installed between the lifting plate 2 and the opening. One lifting plate 2 has two motors 4 mounted on it, with the output ends of the motors 4 penetrating through the lifting plate 2. The other lifting plate 2 has two openings and two fixed brackets 5 fixedly connected to it. A fixed column 6 is slidably connected within each opening, and a limit hole is provided on the fixed column 6. A limit rod 7 is slidably connected through the fixed bracket 5, penetrating through the opening and extending into the limit hole. A top plate 8 is fixedly mounted, a spring 9 is mounted on a limiting rod 7, and a turntable 10 is rotatably connected to a fixed column 6. Two locking blocks 11 are fixedly connected to the output ends of the two motors 4 and the two turntables 10. The four locking blocks 11 are arranged in pairs, and a winding roller 12 is positioned between two locking blocks 11. Both ends of the winding roller 12 have slots, and the locking blocks 11 are located within these slots. The electric cylinder 3, lifting plate 2, motor 4, and two winding rollers 12 are used for continuous winding operations, saving time when changing the winding rollers 12. The limiting rod 7, spring 9, and fixed column 6 are used for quick replacement of the winding rollers 12, avoiding the use of bolts for limiting and improving practicality.

[0027] Two sliding grooves are provided in the opening, and sliders 13 are slidably connected in the sliding grooves. The lifting plate 2 is fixedly connected between the two sliders 13 to improve the stability of the lifting plate 2.

[0028] Two fixed blocks 14 are fixedly connected to the support base 1. A rotating shaft 15 is rotatably connected between the two fixed blocks 14. Two limiting discs 16 are fixedly sleeved on the rotating shaft 15 to limit and guide the film, so as to make the film roll up more neatly.

[0029] Pull rings 17 are fixedly connected to both the limiting rod 7 and the fixing post 6, which are used to facilitate people to pull the limiting rod 7 and the fixing post 6.

[0030] A base 18 is fixedly connected to the support 1, and an anti-slip pad is fixedly connected to the base 18 to improve the stability of the overall device and to increase the friction with the ground.

[0031] It should be further explained that the electric cylinder 3 and motor 4 in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method and electrical connection method can be adjusted and operated by those skilled in the art according to the requirements of their instruction manual, and will not be described in detail here. The electric cylinder 3 and motor 4 are equipped with matching control switches. The installation position of the control switches can be selected according to actual usage needs to facilitate operation and control by the operator.

[0032] In summary, the working principle and process of this film stretching and winding machine are as follows: First, place the film stretching and winding machine at the desired location. Then, place the film on the rotating shaft 15 and wind it around the upper take-up roller 12. Start the motor 4, which drives the clamping block 11, the take-up roller 12, and the turntable 10 to rotate, winding the film. After winding, the operator disconnects the film and starts the electric cylinder 3, causing it to lift the lifting plate 2 and the take-up roller 12. At this point, the lower take-up roller 12 moves back to where the upper take-up roller 12 was. At the designated position, the worker winds the film onto the take-up roller 12 and starts the corresponding motor 4 to wind the film. During this process, the worker pulls the limit rod 7, causing it to move out of the limit hole. At the same time, the limit rod 7 also moves the top plate 8 to compress the spring 9. Then, the fixing post 6 is pulled out, which in turn moves the turntable 10 and the locking block 11. The locking block 11 moves out of the locking slot. At this point, another worker supports the wound film and removes the take-up roller 12. A new take-up roller 12 is then installed. This device is simple and quick to operate and has high practicality.

[0033] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
