Description

Technical Field

[0001] This utility model relates to the field of air guide shroud technology, specifically an air guide shroud for a plastic pellet cooling fan. Background Technology

[0002] In the production and processing of plastic granules, cooling fans are key equipment for achieving rapid cooling and shaping of plastic granules, while air guides, as core components that guide the direction of airflow, directly affect the cooling efficiency and the quality of plastic granules through their angle adjustment flexibility.

[0003] Based on the above, the inventors have discovered the following problems: Currently, most plastic granule cooling fan guide covers on the market adopt a fixed mechanism design. This structure means that the angle of the guide cover is fixed after installation, and cannot be flexibly adjusted according to actual production needs. In actual operation, although the direction of the fan blades can be adjusted, it is difficult to fully and accurately control the coverage and angle of the airflow by simply changing the direction of the fan blades. When faced with such complex working conditions, the fixed-angle guide cover often cannot make the airflow evenly and effectively cover every area of ​​plastic granules that needs to be cooled, resulting in insufficient cooling of some plastic granules and affecting product quality.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a plastic pellet cooling fan guide cover in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling fan guide shroud for plastic pellets, so as to solve the problem that the fixed-angle cooling fan guide shroud mentioned in the background art often fails to uniformly and effectively cover every area of ​​plastic pellets that needs to be cooled when facing such complex working conditions.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A cooling fan shroud for plastic granules includes an adjusting mechanism and a main body. The adjusting mechanism includes a mounting base, on both sides of the upper surface of the mounting base, with a support frame fixedly mounted. A transmission box is fixedly mounted on the outer side of one of the support frames. The main body includes a connecting base and an air outlet base. A rotating shaft is mounted on both ends of the connecting base. A pair of rotating shafts are rotatably connected to the opposing surfaces of a pair of support frames. A fan duct is fixedly mounted on one end of the connecting base. A first flange is mounted on one end of the fan duct. A second flange is mounted on one end of the air outlet base. The first flange and the second flange are connected by bolts. A plurality of guide vanes are rotatably connected to the other end of the air outlet base.

[0008] Furthermore, a first worm gear is rotatably connected inside the transmission box, and one side of the central shaft of the first worm gear is connected to one of the rotating shafts.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the first worm gear is connected to the rotating shaft, which can transmit the power in the transmission box to the connecting seat. The smooth rotation of the connecting seat is achieved through the transmission characteristics of the worm gear, ensuring that the overall angle adjustment of the air guide shroud is precise and controllable, and avoiding angle deviation from affecting the cooling effect.

[0010] Furthermore, inside the transmission box, a first worm is rotatably connected to one side of the first worm wheel, and the first worm meshes with the first worm wheel.

[0012] Furthermore, a first drive motor is fixedly installed on the bottom side of the transmission box, and the output end of the first drive motor is connected to the first worm gear transmission.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the first drive motor provides power to the first worm gear, realizing the automatic adjustment of the connecting seat angle without manual operation, reducing labor intensity, and improving the accuracy and efficiency of airflow direction adjustment.

[0014] Furthermore, the inner wall of the air outlet seat is provided with a cavity, and the central shaft of one end of each of the several guide vanes extends into the cavity and is fitted with a second worm gear.

At the same time, the guide vane is driven to rotate synchronously through the second worm gear transmission, ensuring that the angle of each guide vane is consistent and the air outlet is uniform.

[0016] Furthermore, a connecting shaft is rotatably connected to one side of the cavity, and a second worm is fitted on one side of the connecting shaft located on the second worm wheel, with the second worm meshing with the second worm wheel.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the second worm on the connecting shaft meshes with each second worm wheel, which can synchronously drive all guide vanes to rotate, ensuring that the adjustment angle of each guide vane is consistent, making the air outlet direction uniform and improving the wind power utilization rate. At the same time, the self-locking property of the worm wheel and worm gear transmission can fix the position of the guide vanes and avoid the angle change caused by wind impact.

[0018] Furthermore, a second drive motor is fixedly installed on one side of the upper end of the air outlet seat, and the output end of the second drive motor is connected to the connecting shaft for transmission.

[0020] Furthermore, the interior of the air duct is provided with a cross-shaped groove, and a filter screen is slidably inserted inside the cross-shaped groove.

[0021] The beneficial effects of adopting the above-mentioned further solution are that the cross-shaped groove inside the air duct facilitates the sliding installation and removal of the filter screen, the filter screen can filter impurities in the air and prevent them from entering the fan or adhering to the plastic particles and affecting product quality. At the same time, the groove design makes it easier to clean and replace the filter screen and ensures smooth ventilation.

[0022] Furthermore, a third flange is fixedly installed at the other end of the connecting seat, and a corrugated connecting pipe is installed on the third flange by bolts.

[0023] The beneficial effects of adopting the above-mentioned further solution are that the corrugated connecting pipe of the third flange connection has good flexibility, can adapt to the rotation adjustment of the connecting seat, avoid pipe twisting and damage, and at the same time enhance the connection sealing between the air guide shroud and the fan, reduce wind power loss, and improve cooling efficiency.

The connecting seat 201 can rotate as a whole through the rotating shaft 105, which facilitates the adjustment of the air guiding direction. The air duct 202 and the air outlet seat 206 are bolted to the first flange 205 and the second flange 207, which is convenient for disassembly and assembly. The several guide vanes 209 can adjust the air outlet angle, so that the air force of the plastic granule cooling fan can be accurately applied to the target area, improving the cooling efficiency. The system takes into account both adjustment flexibility and installation convenience.

[0033] Please see Figure 1 - Figure 5The transmission box 103 is rotatably connected to a first worm gear 106. One side of the central shaft of the first worm gear 106 is connected to one of the rotating shafts 105. A first worm 107 is rotatably connected to one side of the first worm gear 106 inside the transmission box 103. The first worm 107 meshes with the first worm gear 106. A first drive motor 104 is fixedly mounted on the bottom side of the transmission box 103. The output end of the first drive motor 104 is connected to the first worm 107. The inner wall of the air outlet seat 206 has a cavity 212. One end of the central shaft of several guide vanes 209 extends into the cavity 212 and is fitted with a second worm gear 210. A connecting shaft 213 is rotatably connected to one side of the cavity 212. The second worm gear 210 is mounted on the connecting shaft 213. A second worm gear 211 is fitted on one side of the 10, and the second worm gear 211 meshes with the second worm wheel 210. A second drive motor 208 is fixedly installed on one side of the upper end of the air outlet seat 206. The output end of the second drive motor 208 is connected to the connecting shaft 213 for transmission.

A third flange 203 is fixedly installed on the other end of the connecting seat 201. A corrugated connecting pipe 204 is installed on the third flange 203 by bolts. The first worm wheel 106 is connected to the rotating shaft 105, which can transmit the power in the transmission box 103 to the connecting seat 201. The transmission characteristics of the worm wheel and worm gear realize the smooth rotation of the connecting seat 201, ensuring the air guide. The overall angle adjustment of the cover is precise and controllable, avoiding angle deviation that could affect the cooling effect. The first worm gear 107 meshes with the first worm wheel 106, utilizing the self-locking property of the worm gear transmission to stably maintain the current position after adjusting the angle of the connecting seat 201, preventing angle changes due to external forces. The first drive motor 104 provides power to the first worm gear 107, realizing automated adjustment of the angle of the connecting seat 201 without manual operation, reducing labor intensity and improving the accuracy and efficiency of airflow direction adjustment. The central axis of the guide vane 209 extends into the cavity 212 and is fitted with the second worm wheel 210, so that the transmission structure is hidden inside the air outlet seat 206, avoiding contact with the outside environment that could cause wear or interference. At the same time, the second worm wheel 210 drives the guide vane 209 to rotate synchronously, ensuring... To ensure consistent angles of all guide vanes 209 and uniform airflow, the second worm gear 211 on the connecting shaft 213 meshes with each second worm wheel 210, synchronously driving all guide vanes 209 to rotate. This ensures consistent adjustment angles of all guide vanes 209, unifying the airflow direction and improving wind power utilization. Simultaneously, the self-locking property of the worm gear transmission fixes the position of the guide vanes 209, preventing angle changes caused by wind impact. The second drive motor 208 drives the connecting shaft 213 to rotate, achieving automated adjustment of the guide vane 209 angles. This allows for rapid adjustment of the airflow angle according to the cooling requirements of the plastic granules, optimizing the cooling effect and adapting to different working conditions. The cross-shaped groove 214 inside the air duct 202 facilitates the sliding installation and removal of the filter screen 215, which filters impurities from the air.To prevent it from entering the fan or adhering to the plastic granules and affecting product quality, the sliding groove design makes cleaning and replacement of the filter screen 215 more convenient, ensuring smooth ventilation. The corrugated connecting pipe 204 connected to the third flange 203 has good flexibility, which can adapt to the rotation adjustment of the connecting seat 201, avoiding pipe twisting and damage. At the same time, it enhances the connection and sealing between the air guide shroud and the fan, reduces airflow loss, and improves cooling efficiency.

[0034] Specifically, the working principle of this type of plastic granule cooling fan guide shroud is as follows: During use, the overall structure is fixed by the mounting base 101 and the support frame 102. The user can fix the equipment in a suitable position through the mounting holes at both ends of the mounting base 101. The corrugated connecting pipe 204 connected to the third flange 203 guides the fan airflow into the connecting base 201 and the air duct 202. The filter screen 215 inside the air duct 202 is installed along the cross-shaped sliding groove 214 to filter impurities in the air. When the airflow direction needs to be adjusted, the first drive motor 104 drives the first worm gear 107 inside the transmission box 103 to rotate, causing the first worm wheel 106 and the rotating shaft 105 to rotate synchronously, thus connecting... The connecting seat 201, the air duct 202, and the air outlet seat 206 rotate as a whole, enabling a wide range of adjustment of the air guide angle. At the same time, the second drive motor 208 drives the connecting shaft 213 in the cavity 212 of the air outlet seat 206 to rotate, causing the second worm gear 211 to drive the second worm wheel 210 to rotate, thereby synchronously adjusting the angle of several guide vanes 209 and controlling the air outlet direction. The air duct 202 and the air outlet seat 206 are easily disassembled and assembled via the first flange 205 and the second flange 207. The corrugated connecting pipe 204 deforms flexibly as the connecting seat 201 rotates, ensuring that the air force is efficiently transmitted to the plastic granule cooling area, thus achieving precise guidance and efficient utilization of the air force as a whole.
