Description

Technical Field

[0001] This utility model belongs to the field of mulch film processing technology, and in particular relates to a multifunctional blowing film device for controlling air volume in mulch film processing. Background Technology

[0002] This multi-functional blown film device for processing plastic mulch film is mainly used to precisely adjust the blown film air volume and air pressure during the production process of plastic mulch film. Through intelligent or mechanical air volume control system, it stabilizes the film bubble forming environment, ensuring that the mulch film is of uniform thickness and width. Its function is to optimize cooling efficiency, improve the physical properties of the film (such as tensile strength and light transmittance), adapt to different raw material and process requirements, reduce energy consumption and scrap rate, and ultimately achieve efficient and high-quality continuous production of mulch film.

[0003] The existing multi-functional blown film device for mulch film processing still has some problems during use. For example, the air volume cannot be adjusted during use, which makes it impossible to flexibly adjust the air pressure and air volume according to different raw material characteristics, film thickness or environmental conditions during production. This makes it difficult to control the cooling rate and forming stability of the film bubble, which can easily cause problems such as uneven film thickness, rough surface or insufficient strength, seriously affecting product quality and production efficiency.

[0004] To address these issues, we provide a multifunctional blown film device for controlling airflow in mulch film processing. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional blowing film device for mulch film processing that controls the air volume, thereby solving the problem that existing multifunctional blowing film devices for mulch film processing cannot control the air volume.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a multifunctional blown film device for controlling airflow in mulch film processing. It includes a base plate, an extrusion device on the top of the base plate, a blower fixedly connected to the top of the extrusion device, a ventilation box connected to the top of the blower, a suction pipe connected to the top of the ventilation box, a drive motor fixedly connected inside the ventilation box, a drive rod fixedly connected to the output end of the drive motor, a gear fixedly connected to the top of the drive rod, a gear disc rotatably connected inside the ventilation box, a sealing plate fixedly connected to the top of the gear disc, a sealing ring fixedly connected to the top of the sealing plate, a circular plate fixedly connected to the top of the gear disc, a wind baffle fixedly connected to the surface of the circular plate, and a ventilation slot on the top of the ventilation box.

[0008] The present invention is further configured such that a limiting block is fixedly connected to the top of the ventilation box, a limiting groove is opened at the bottom of the circular plate, and the circular plate is slidably connected to the surface of the limiting plate through the limiting groove.

[0009] The present invention is further configured such that a sealing groove is provided at the top of the inner cavity of the ventilation box, and the sealing ring is slidably connected inside the sealing groove, thereby sealing the ventilation box.

[0010] The present invention is further provided that the bottom of the ventilation box is provided with a through groove for communicating with a blower.

[0011] The present invention is further configured such that the sealing ring is made of rubber, and the rubber is used to seal the ventilation box.

[0012] The present invention is further configured such that an extrusion groove is provided on the top of the extrusion device, and the extrusion groove is used to extrude mulch film raw material.

[0013] The present invention is further configured such that a support rod is fixedly connected to the top of the base plate, and the support rod is used to fix the extrusion device.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a transmission motor to drive a gear and a toothed disc to rotate the baffle plate, which can precisely adjust the opening and closing of the ventilation slot and achieve precise control of the blown film air volume. This solves the problem that traditional devices cannot adjust the blowing volume. In addition, the sliding sealing structure of the rubber sealing ring and the sealing groove effectively prevents air leakage and ensures stable air pressure under different raw materials and process conditions, thereby improving the quality of film bubble forming, making the film thickness more uniform and the surface smoother, while reducing energy consumption and production scrap rate.

[0016] 2. This utility model prevents airflow leakage during the rotation of the wind baffle by sliding the rubber sealing ring and the sealing groove, combined with the guiding structure of the limiting block and the limiting groove. This ensures stable air pressure inside the ventilation box, avoids the air volume fluctuation problem caused by air leakage in traditional devices, and improves the reliability and durability of the equipment, enabling continuous and efficient mulch film production.

It includes a base plate 1, which can fix an extrusion device 2 and a blower 3. The extrusion device 2 is mounted on the top of the base plate 1, and the blower 3 is fixedly connected to the top of the extrusion device 2. A ventilation box 4 is connected to the top of the blower 3, and a suction pipe 5 is connected to the top of the ventilation box 4. The suction pipe 5 can remove the heat generated during extrusion. A drive motor 6 is fixedly connected inside the ventilation box 4, and a drive rod 7 is fixedly connected to the output end of the drive motor 6. The drive rod 7 can drive a gear 8 to rotate, and its bottom is fixedly connected to the output end of the drive motor 6. The gear 8 is fixedly connected to the bottom of the transmission rod 7, and the gear 8 is fixedly connected to the top of the transmission rod 7.

The top of the surface of the gear 9 is fixedly connected to the sealing plate 10, and the top of the sealing plate 10 is fixedly connected to the sealing ring 11. The sealing plate 10 and the sealing ring 11 can prevent air leakage inside the ventilation box 4, thereby affecting the air pressure. The top of the gear 9 is fixedly connected to the circular plate 12, and the surface of the circular plate 12 is fixedly connected to the wind baffle 13. The top of the ventilation box 4 is provided with a ventilation slot 14. The air volume can be adjusted by adjusting the overlap between the wind baffle 13 and the ventilation slot 14.

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, a limiting block 15 is fixedly connected to the top of the ventilation box 4, and a limiting groove 16 is opened at the bottom of the circular plate 12. The circular plate 12 is slidably connected to the surface of the limiting plate through the limiting groove 16. The limiting groove 16 and the limiting plate can limit the circular plate 12 to ensure that it will not deviate when rotating. A sealing groove 17 is opened at the top of the inner cavity of the ventilation box 4, and a sealing ring 11 is slidably connected inside the sealing groove 17. The sealing ring 11 is used to seal the ventilation box 4. The sealing groove 17 and the sealing ring 11 can seal the ventilation box 4.

[0030] The working principle of this utility model is as follows: When it is necessary to adjust the air volume, the user starts the transmission motor 6 through the external controller. The transmission motor 6 drives the gear 8 to rotate through the transmission rod 7. The gear 8 meshes with the gear plate 9, so that the gear plate 9 rotates synchronously. The gear plate 9 drives the circular plate 12 to rotate, and the circular plate 12 drives the wind baffle 13 to rotate. By changing the overlap between the wind baffle 13 and the ventilation groove 14, the effective opening area of ​​the ventilation groove 14 is dynamically adjusted, thereby accurately controlling the air volume and adapting to different film thicknesses and raw material requirements.

[0031] Meanwhile, during the adjustment process, the sealing plate 10 and the rubber sealing ring 11 slide along the sealing groove 17 of the inner cavity of the ventilation box 4 to ensure that there is no leakage of airflow during rotation, maintain a stable wind pressure environment, and prevent the circular plate 12 from shifting by the cooperation of the limiting block 15 with the limiting groove 16 at the bottom of the circular plate 12, thus ensuring the accuracy of the rotation trajectory of the wind baffle 13.
