Description

Technical Field

[0001] The utility model belongs to the technical field of plastic film rolling, in particular to a PE plastic film rolling mechanism which is easy to adjust. Background Art

[0002] PE plastic film has good barrier properties and can prevent the penetration of water vapor, oxygen, etc. It is often used in food and medicine packaging and can effectively extend the shelf life. It has good flexibility and can be used as ground film in agriculture to keep warm, moisturize, and inhibit weed growth. In industry, it can be used to protect products and prevent them from being scratched and damp during transportation and storage. It is a widely used, economical and practical film material. In the production and winding process of PE plastic film, ensuring that the plastic film is in the right state is crucial to product quality and production efficiency. Traditional winding mechanisms often find it difficult to accurately adjust the tension of the plastic film. If the PE plastic film is too loose when winding, wrinkles are likely to occur. If it is too tight, the plastic film will be damaged, such as tiny cracks, which will affect subsequent use and storage. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides an easily adjustable PE plastic film winding mechanism, which solves the problem that traditional winding mechanisms often find it difficult to accurately adjust the tightness of the plastic film. If the PE plastic film is too loose when winding, wrinkles are likely to occur, and if it is too tight, the plastic film may be damaged, such as tiny cracks, which will affect subsequent use and storage.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PE plastic film winding mechanism that is easy to adjust, comprising a base, a fixed frame fixedly connected to the top of the base at its center position, two telescopic rods fixedly connected to the top of the fixed frame, one end of the telescopic rod passes through one side of the fixed frame and is fixedly connected to a support block at the end, one end of the support block is slidably connected to a connecting rod, an extrusion spring is attached to the outer sleeve of the connecting rod, an end of the connecting rod away from the support block is fixedly connected to the connecting block, one side of the connecting block is fixedly connected to a limiting plate, there are two limiting plates, and a squeezing roller is rotatably connected between the two limiting plates, two support rods are symmetrically fixed above the base near its end position, and a conveying roller is rotatably connected between the two support rods.

[0005] As a further solution of the present invention: a pillar is fixedly connected to the top of the support rod, a baffle is fixedly connected to the other end of the pillar, and a sliding sleeve is slidably connected to the outside of the pillar.

[0006] As a further solution of the present invention: the outer wall of the pillar is located between the sliding sleeve and the baffle and is sleeved with a compression spring, one end of the compression spring is connected to the baffle, and the other end is connected to the sliding sleeve. There are two sliding sleeves, and a flattening roller is rotatably connected between the two sliding sleeves.

[0007] As a further solution of the present invention: a bracket is fixedly connected to one end of the base above and away from the support rod, and a winding roller is rotatably connected to one side of the bracket.

[0008] As a further solution of the present invention: one end of the flattening roller and the winding roller are both provided with a linkage wheel, the outer walls of the two linkage wheels are sleeved with belts, and one side of one of the linkage wheels is provided with an output motor.

[0009] As a further solution of the present invention: the positions of the flattening roller and the conveying roller correspond to each other, and the flattening roller is located above the conveying roller.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The adjustable PE plastic film winding mechanism is provided with a telescopic rod, a support block, a connecting rod, an extrusion spring, a connecting block and an extrusion roller. During the winding process, the PE plastic film passes under the extrusion roller, and the telescopic rod drives the support block to adjust the height of the extrusion roller, thereby changing the tension of the PE plastic film and keeping the PE plastic film taut. At the same time, when the extrusion roller contacts the PE plastic film, the plastic film is squeezed by the extrusion roller to squeeze the connecting block, and the connecting block squeezes the extrusion spring to drive the connecting rod to slide in the support block. The extrusion spring plays a buffering role. When the plastic film is in a taut state due to adjustment, the extrusion spring can absorb part of the pressure to prevent the extrusion roller from applying excessive pressure on the plastic film and causing damage. Therefore, while ensuring that the plastic film is taut to avoid wrinkles, the plastic film can be protected from damage, thereby improving the quality and efficiency of PE plastic film winding.

[0012] 2. The adjustable PE plastic film winding mechanism is provided with a support rod, a conveying roller, a pillar, a sliding sleeve, a compression spring and a flattening roller. During the winding process, the PE plastic film is passed between the conveying roller and the flattening roller. The conveying roller rotates between the two support rods to convey the PE plastic film. After being squeezed by the PE plastic film, the flattening roller drives the sliding sleeve to slide on the outer wall of the pillar to squeeze the compression spring. The compression spring is squeezed and rebounds, driving the flattening roller above the conveying roller through the sliding sleeve to flatten the PE plastic film, thereby removing wrinkles from the PE plastic film. In this way, not only can a good wrinkle removal effect be achieved and the quality of subsequent PE plastic film winding is guaranteed, but the mechanism can also adapt to fabrics of different thicknesses, thereby improving the practicality of the mechanism.

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, the utility model provides a technical solution: a PE plastic film winding mechanism that is easy to adjust, including a base 1, a fixed frame 2 is fixedly connected to the top of the base 1 at its center position, and two telescopic rods 3 are fixedly connected to the top of the fixed frame 2. Because the telescopic rod 3 is provided, the telescopic rod 3 is extended or shortened to adjust the height of the squeezing roller 9 through the support block 4, so that the mechanism changes the tension state of the PE plastic film when winding, so that the PE plastic film remains tight, and the quality of winding is improved. One end of the telescopic rod 3 passes through one side of the fixed frame 2 and the end is fixedly connected to the support block 4. One end of the support block 4 is slidably connected to the connecting rod 5, and the outer surface of the connecting rod 5 is connected to the extrusion spring 6. Because of the squeezing spring 6, when the squeezing roller 9 squeezes the plastic film, when the plastic film is in a taut state, the squeezing roller 9 will drive the connecting rod 5 to slide in the support block 4 through the connecting block 7, and at the same time squeeze the squeezing spring 6. The squeezing spring 6 can absorb part of the pressure to prevent the squeezing roller 9 from applying excessive pressure to the plastic film and causing damage. The end of the connecting rod 5 away from the support block 4 is fixedly connected to the connecting block 7, and one side of the connecting block 7 is fixedly connected to the limiting plate 8. There are two limiting plates 8, and the squeezing roller 9 is rotatably connected between the two limiting plates 8. Two support rods 10 are symmetrically fixed above the base 1 near its end position, and a conveying roller 11 is rotatably connected between the two support rods 10;

[0020] The support rod 10 is fixedly connected to a pillar 12 above, and the other end of the pillar 12 is fixedly connected to a baffle 13. The outer sliding of the pillar 12 is connected to a sliding sleeve 14. The outer wall of the pillar 12 is located between the sliding sleeve 14 and the baffle 13 and is sleeved with a compression spring 15. Due to the provision of the compression spring 15, the arrangement of the compression spring 15 enables the flattening roller 16 to adaptively adjust the pressure between it and the conveying roller 11. When the thickness of the plastic film changes, the flattening roller 16 can move up and down under the action of the compression spring 15 to maintain appropriate pressure on the plastic film. One end of the compression spring 15 is connected to the flattening roller 16. The baffle 13 is connected to the baffle 13, and the other end is connected to the sliding sleeve 14. There are two sliding sleeves 14. A flattening roller 16 is rotatably connected between the two sliding sleeves 14. The positions of the flattening roller 16 and the conveying roller 11 correspond. The flattening roller 16 is located above the conveying roller 11. Due to the provision of the flattening roller 16, the PE plastic film passes between the conveying roller 11 and the flattening roller 16. The flattening roller 16 applies pressure from above, which can effectively remove wrinkles that may be generated in the plastic film in the previous process, so that the PE plastic film enters the subsequent winding process more smoothly, thereby improving the quality of the wound product.

[0021] A bracket 17 is fixedly connected to one end of the base 1 away from the support rod 10 above, and a winding roller 18 is rotatably connected to one side of the bracket 17. One end of the flattening roller 16 and the winding roller 18 is provided with a linkage wheel 19, and the outer walls of the two linkage wheels 19 are sleeved with a belt 20. An output motor 21 is provided on one side of one of the linkage wheels 19. Through the cooperation between the linkage wheel 19 and the belt 20, the power of the output motor 21 can be effectively transmitted to the flattening roller 16 and the winding roller 18, so that the flattening roller 16 and the winding roller 18 rotate synchronously at a certain speed ratio, which helps to maintain uniform tension of the plastic film during the transmission and winding process, and ensures the winding effect of the PE plastic film.

[0022] The working principle of the utility model is as follows: when using this mechanism, the PE plastic film passes between the conveying roller 11 and the flattening roller 16, and the flattening roller 16 is squeezed by the PE plastic film to drive the sliding sleeve 14 to slide on the outer wall of the pillar 12 to squeeze the compression spring 15. The compression spring 15 rebounds and drives the flattening roller 16 to cooperate with the conveying roller 11 to flatten the PE plastic film. The PE plastic film then passes under the squeezing roller 9, and the height of the support block 4 is adjusted by the telescopic rod 3 to drive the squeezing roller 9 to squeeze the PE plastic film, so that the PE plastic film is in a taut state. At the same time, the taut state of the PE plastic film drives the squeezing roller 9 to squeeze the connecting block 7, and the connecting block 7 slides in the support block 4 to squeeze the squeezing spring 6. The squeezing spring 6 absorbs part of the pressure of the squeezing roller 9 on the PE plastic film, and finally the PE plastic film is wound on the winding roller 18, and the output motor 21 is started. The output motor 21 drives one of the linkage wheels 19 to rotate, and under the cooperation of the linkage wheel 19 and the belt 20, the winding roller 18 and the conveying roller 11 rotate synchronously for winding.
