Description

Technical Field

[0001] This utility model relates to the technical field of polypropylene casting film equipment, specifically a polypropylene casting film cooking equipment. Background Technology

[0002] Cast polypropylene film (CPP) is a polypropylene film produced using a casting process. It can be divided into general-purpose CPP film, aluminized CPP film, and retort grade CPP film. Among them, retort grade CPP film is generally between 60 and 80 μm thick, can withstand high-temperature cooking at 121°C for 30 minutes, has good oil resistance and airtightness, and has high heat-sealing strength. Retort grade CPP film is generally used for the inner layer of meat packaging.

[0003] In existing technologies, such as the "A Cooking Polypropylene Cast Film Equipment" with Chinese Patent Publication No. CN219636490U, the internal adjustment mechanism can be used for connection and fixation during operation. This allows the internal circular column to be engaged and fixed with the vertical plate frame. During use, the internal right circular column is connected to the rotating shaft, and a connected motor is used for operation. The motor rotates the internal circular column, and the angle of the auxiliary column is adjusted. The material in contact with the upper part is positioned by the auxiliary column, and the material above the lower winding shaft is wound in the center. This solves the problem that the internal polypropylene material is not easy to wind up, and the material wound on the surface of the winding shaft is prone to deviation.

[0004] In the aforementioned prior art, the internal polypropylene material is wound without shifting. However, during the winding process, as the wound polypropylene product becomes increasingly thicker while the rotation speed of the winding motor remains constant, the tensile strength of the polypropylene product increases, which can easily lead to tensile damage and reduce product quality. Utility Model Content

[0005] The purpose of this invention is to provide a polypropylene casting film cooking device with adjustable conveying tension.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polypropylene casting film cooking device, comprising two support frames fixedly installed on the top of a base, a first electric telescopic rod fixedly installed on the inner side of each of the two support frames, a pressure sensor fixedly installed at the top of the first electric telescopic rod, a movable frame slidably installed on the top of the support frame, a top block fixedly installed on the inner side of the movable frame, the top of the pressure sensor contacting and pressing the bottom of the top block, and a support roller rotatably installed between the two movable frames.

[0007] To facilitate the adjustment of tension, in a preferred embodiment of the polypropylene casting film cooking equipment of this utility model, a sliding groove is provided on the inner side of the first electric telescopic rod, and the movable frame is slidably installed with the sliding groove.

[0008] For ease of transport, in a preferred embodiment of the polypropylene casting film cooking equipment of this utility model, fixed rods are fixedly installed on both the left and right sides of the support frame, and guide rollers are rotatably installed between the two fixed rods, with the two guide rollers arranged symmetrically with respect to the support roller.

[0009] To facilitate the winding operation, in a preferred embodiment of the polypropylene casting film cooking equipment of this utility model, two mounting blocks are fixedly installed on the top of the base. The mounting blocks are located on the right side of the support frame, and a support rod is fixedly installed on the left side of the mounting blocks. An adjusting roller is installed between the two support rods.

[0010] To facilitate further winding operations, in a preferred embodiment of the polypropylene casting film cooking equipment of this utility model, a motor is fixedly installed on one side of the mounting block, and the output end of the motor is connected to a winding roller.

[0011] To facilitate adjustment of the winding position, in a preferred embodiment of the polypropylene casting film equipment of this utility model, a movable column is rotatably installed on the inner side of the adjusting roller, and the movable column passes through the support rod and is slidably sleeved.

[0012] To facilitate further adjustment of the winding position, in a preferred embodiment of the polypropylene casting film equipment of this utility model, a second electric telescopic rod is fixedly installed on one side of the support rod, a connecting block is fixedly installed at one end of the movable column, and the output end of the second electric telescopic rod is fixedly installed with the connecting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The polypropylene film product is supported by a support roller, which causes the top block inside the movable frame to apply pressure to the pressure sensor. The pressure sensor can detect the tension of the polypropylene film product during the winding process. When the detected pressure exceeds the preset threshold of the pressure sensor, the first electric telescopic rod retracts, causing the pressure sensor to move downward. This reduces the contact pressure between the support roller and the polypropylene film product, thereby adjusting the tension of the winding of the polypropylene film product and improving the production quality of the polypropylene film product.

[0017] Please see Figures 1 to 4 A polypropylene casting film cooking device includes two support frames 2 fixedly installed on the top of a base 1. A first electric telescopic rod 6 is fixedly installed on the inner side of each of the two support frames 2. A pressure sensor 9 is fixedly installed on the top of the first electric telescopic rod 6. A movable frame 8 is slidably installed on the top of the support frame 2. A top block 10 is fixedly installed on the inner side of the movable frame 8. The top of the pressure sensor 9 contacts and presses against the bottom of the top block 10. A support roller 11 is rotatably installed between the two movable frames 8.

[0018] In this embodiment: by setting a first electric telescopic rod 6 and a pressure sensor 9, the polypropylene film product is supported and conveyed by the support roller 11. The pressure sensor 9 is pressed by the top block 10 inside the movable frame 8. The pressure sensor 9 can detect the tension of the polypropylene film product in real time during the winding process. When the detected pressure exceeds the preset pressure threshold of the pressure sensor 9, the first electric telescopic rod 6 retracts, causing the pressure sensor 9 to move downward, thereby reducing the contact pressure between the support roller 11 and the polypropylene film product. When the detected pressure is less than the preset pressure threshold of the pressure sensor 9, the first electric telescopic rod 6 extends, causing the pressure sensor 9 to move upward, thereby increasing the contact pressure between the support roller 11 and the polypropylene film product. This allows for real-time adjustment of the tension of the polypropylene film product during winding, facilitating the winding operation.

[0019] As a technical optimization of this utility model, a groove 7 is provided on the inner side of the first electric telescopic rod 6, and the movable frame 8 is slidably installed with the groove 7.

[0020] In this embodiment: by setting the slide groove 7, the first electric telescopic rod 6 can drive the pressure sensor 9 and the movable frame 8 to adjust their height along the slide groove 7.

[0021] As a technical optimization of this utility model, a fixing rod 4 is fixedly installed on both the left and right sides of the support frame 2, and a guide roller 5 is rotatably installed between the two fixing rods 4. The two guide rollers 5 are symmetrically arranged with respect to the support roller 11.

[0022] In this embodiment: By setting guide rollers 5, it is convenient to transport and wind polypropylene film products by means of the cooperation between support rollers 11 and two guide rollers 5.

[0023] As a technical optimization of this utility model, two mounting blocks 3 are fixedly installed on the top of the base 1. The mounting blocks 3 are located on the right side of the support frame 2. A support rod 14 is fixedly installed on the left side of the mounting blocks 3. An adjusting roller 17 is installed between the two support rods 14. A motor 12 is fixedly installed on one side of the mounting blocks 3. The output end of the motor 12 is connected to a winding roller 13.

[0024] In this embodiment: by setting the adjusting roller 17, when the motor 12 drives the winding roller 13 to rotate and wind up the polypropylene film product, the winding adjustment of the polypropylene film product by the adjusting roller 17 can make the polypropylene film product wrap flatly around the outside of the winding roller 13 for winding operation.

[0025] As a technical optimization of this utility model, a movable column 16 is rotatably installed on the inner side of the adjusting roller 17. The movable column 16 passes through the support rod 14 and is slidably sleeved. A second electric telescopic rod 15 is fixedly installed on one side of the support rod 14. A connecting block 18 is fixedly installed on one end of the movable column 16. The output end of the second electric telescopic rod 15 is fixedly installed with the connecting block 18.

[0026] In this embodiment: by setting a second electric telescopic rod 15, it is convenient to drive the connecting block 18 to move. The connecting block 18 drives the movable column 16 to slide along the fixed rod 4, thereby fine-tuning the position of the polypropylene film product through the adjusting roller 17 on the outside of the movable column 16, so that the polypropylene film product can be aligned with the winding roller 13, which facilitates the winding operation of the polypropylene film product by the winding roller 13.

[0027] Working principle: First, according to Figure 4 The polypropylene film is passed through guide roller 5, support roller 11, guide roller 5, and adjusting roller 17, and then wound around the outside of take-up roller 13 for winding. The second electric telescopic rod 15 is activated to extend and retract, causing the connecting block 18 and movable column 16 to move. The movable column 16 drives the adjusting roller 17 to fine-tune the position of the polypropylene film, ensuring it is aligned and wound around the outside of take-up roller 13. The motor 12 is then activated to rotate the take-up roller 13 to wind the polypropylene film. When the pressure detected by pressure sensor 9 exceeds a preset threshold, the first electric telescopic rod 6 retracts, causing pressure sensor 9 to move downwards, reducing the contact pressure between support roller 11 and the polypropylene film. When the pressure detected by pressure sensor 9 is less than the preset threshold, the first electric telescopic rod 6 extends, causing pressure sensor 9 to move upwards, increasing the contact pressure between support roller 11 and the polypropylene film. This allows for real-time adjustment of the tension during the winding of the polypropylene film, ensuring proper winding operation.
