Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE film processing technology, specifically a PE film drying device. Background Technology
[0002] PE film, or polyethylene film, refers to film produced from PE granules. PE film is moisture-proof and has low moisture permeability. Depending on the manufacturing method and control measures, polyethylene film (PE) can be produced into products with different properties, such as low-density, medium-density, high-density polyethylene, and cross-linked polyethylene. Low-density polyethylene film has good transparency and heat-sealing properties, and is waterproof and moisture-proof.
[0003] In the production and processing of PE film (polyethylene film), it is often necessary to dry the printed, coated, or laminated PE film to remove surface solvents or moisture, ensuring the quality of the film and its subsequent processing performance. Traditional PE film drying equipment usually uses hot air drying, but existing equipment has the following shortcomings:
[0004] 1. Uneven drying: Uneven distribution of hot air can easily lead to localized overheating or incomplete drying of the PE film, affecting the film's flatness and physical properties.
[0005] 2. Prone to wrinkles: PE film lacks an effective guiding and flattening structure during the drying process. The film is prone to wrinkles and curling due to hot air impact or changes in its own tension, which reduces the product qualification rate. Utility Model Content
[0006] The purpose of this invention is to provide a PE film drying device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a PE film drying device, comprising a support plate, a housing fixedly connected to the top of the support plate, a drying mechanism disposed inside the housing, and a guide mechanism disposed at the bottom of the drying mechanism;
[0008] The drying mechanism includes a mounting shell, which is fixedly connected to the top of the housing. Support shafts are fixedly connected to both sides inside the mounting shell. Heating wires are fixedly connected to the surface of each support shaft. A fan is provided at the bottom of the support shaft and is fixedly connected to the mounting shell.
[0009] The guiding mechanism includes placement slots, which are all located on both sides of the housing. A support frame is fixedly connected inside the placement slot. A first guide roller and a second guide roller are rotatably connected inside the support frame. The first guide roller and the second guide roller are used to guide the PE film smoothly through the inside of the housing, and at the same time play a flattening role to prevent the film from wrinkling or shifting during the drying process.
[0010] Preferably, two fans are provided, which are symmetrically arranged and fixedly connected by a fixing rod. The two symmetrically arranged fans can make the hot air blow more evenly onto the PE film surface, avoiding local overheating or insufficient drying. The fixing rod is used to connect the two fans, enhance the structural stability, and prevent vibration or displacement during fan operation.
[0011] Preferably, a connecting pipe is fixedly connected to one side of the mounting shell, and a fan is fixedly connected to the side of the connecting pipe opposite to the mounting shell. A horizontal plate is fixedly connected to the bottom of the fan and the horizontal plate is fixedly connected to the surface of the shell. The fan sends external air into the mounting shell through the connecting pipe to form a continuous hot air circulation. The horizontal plate is used to fix the fan, ensure its stable operation, and reduce the impact of vibration on the device.
[0012] Preferably, the first guide roller and the second guide roller have the same specifications, and the top and bottom of the support frame are fixedly connected with connecting plates. The consistent specifications of the guide rollers can ensure that the PE film is subjected to uniform force on both the upper and lower sides, and avoid the film from running off-center or stretching unevenly due to the difference in roller diameter. The connecting plates are used to enhance the overall rigidity of the support frame, prevent deformation after long-term use, and ensure the stability and reliability of the guiding mechanism.
[0013] Preferably, the left side of the housing has an installation groove, and a detachable baffle is inserted into the installation groove. The detachable baffle can seal the housing during the drying process, reduce heat loss, and improve drying efficiency; at the same time, it can be removed when needed for convenient maintenance or cleaning of the interior.
[0014] Compared with the prior art, the present invention provides a PE film drying device, which has the following beneficial effects:
[0015] This PE film drying device, by setting up a drying mechanism, sends external air into the installation shell through a connecting pipe via a fan. After the air comes into contact with the heating wire, it becomes hot air, which is then blown evenly onto the surface of the PE film inside the shell by a fan, making the hot air distribution more uniform and significantly improving the drying effect and efficiency.
[0016] This PE film drying device, by setting a guiding mechanism including a first guide roller and a second guide roller, allows the PE film to pass through the placement grooves on both sides of the housing and be clamped between the upper and lower guide rollers. This not only provides stable guidance but also flattens the film, preventing wrinkles or displacement caused by hot air or tension changes during the drying process. Attached Figure Description

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] This utility model provides a technical solution: Example
[0025] Combination Figures 1-3 A PE film drying device includes a support plate 1, a housing 4 fixedly connected to the top of the support plate 1, a drying mechanism 2 disposed inside the housing 4, and a guide mechanism 3 disposed at the bottom of the drying mechanism 2.
[0026] The drying mechanism 2 includes a mounting shell 21, which is fixedly connected to the top of the housing 4. Support shafts 28 are fixedly connected to both sides inside the mounting shell 21. Heating wires 22 are fixedly connected to the surface of the support shafts 28. A fan 27 is provided at the bottom of the support shafts 28 and is fixedly connected to the mounting shell 21.
[0027] Furthermore, two fans 27 are provided, arranged symmetrically, and a fixing rod 23 is fixedly connected between the two fans 27. The two symmetrically arranged fans 27 can make the hot air blow more evenly onto the PE film surface, avoiding local overheating or insufficient drying. The fixing rod 23 is used to connect the two fans 27, enhance the structural stability, and prevent the fans 27 from vibrating or displacing during operation.
[0028] Furthermore, a connecting pipe 25 is fixedly connected to one side of the mounting shell 21, and a fan 24 is fixedly connected to the side of the connecting pipe 25 away from the mounting shell 21. A horizontal plate 26 is fixedly connected to the bottom of the fan 24 and is fixedly connected to the surface of the shell 4. The fan 24 sends external air into the mounting shell 21 through the connecting pipe 25 to form a continuous hot air circulation. The horizontal plate 26 is used to fix the fan 24 to ensure its stable operation and reduce the impact of vibration on the device. Example
[0029] See Figure 4 Furthermore, based on Embodiment 1, the guiding mechanism 3 includes a placement groove, which is opened on both sides of the housing 4. A support frame 31 is fixedly connected in the placement groove. A first guide roller 33 and a second guide roller 34 are rotatably connected in the support frame 31. The first guide roller 33 and the second guide roller 34 are used to guide the PE film to pass smoothly through the inside of the housing 4, and at the same time play a flattening role to prevent the film from wrinkling or shifting during the drying process.
[0030] Furthermore, the first guide roller 33 and the second guide roller 34 have the same specifications. The support frame 31 is fixedly connected to the top and bottom with connecting plates 32. The consistent specifications of the guide rollers can ensure that the PE film is subjected to uniform force on both the upper and lower sides, and avoid the film from running off-center or stretching unevenly due to the difference in roller diameter. The connecting plates 32 are used to enhance the overall rigidity of the support frame 31, prevent deformation after long-term use, and ensure the stability and reliability of the guiding mechanism 3.
[0031] Furthermore, a mounting groove is provided on the left side of the housing 4, and a detachable baffle 35 is inserted into the mounting groove. The detachable baffle 35 can seal the housing 4 during the drying process, reduce heat loss, and improve drying efficiency; at the same time, it can be removed when needed for convenient maintenance or cleaning of the interior.
[0032] In actual operation, when this device is used, the PE film is first inserted between the first guide roller 33 and the second guide roller 34 on both sides through the mounting groove opened on the left side of the housing 4. The first guide roller 33 and the second guide roller 34 can guide the PE film and prevent the PE film from wrinkling during the drying process.
[0033] When the PE film needs to be dried, the detachable baffle 35 is inserted into the mounting slot, and the fan 24 is started. The air generated by the fan 24 is delivered to the inside of the mounting shell 21 through the connecting pipe 25. At this time, the air comes into contact with the heating wire 22 and becomes hot air. At the same time, the fan 27 is started. Under the action of the fan 27, the hot air can be quickly transferred to the inside of the shell 4 to achieve the purpose of uniform drying of the PE film.
