Description

Technical Field

[0001] The present invention relates to the technical field of equipment for collecting and rolling films, and in particular to equipment for collecting and rolling films of greenhouse films. Background Art

[0002] Greenhouse film refers to the plastic agricultural film used to make plastic greenhouses and hothouses. After covering, it can provide crops with a microclimate environment with good temperature, humidity and light quality, and can prevent pests and diseases and reduce the impact of natural disasters, thereby increasing crop yield and quality, harvesting earlier and extending the growth cycle. In the production of greenhouse film, collecting and rolling equipment is required. The collecting and rolling equipment is a device used to roll up the greenhouse film. The collecting and rolling equipment is usually composed of a group of rollers and a control system.

[0017] 2. When it is detected that the temperature of the greenhouse film is high, the inclined plate will move outward and drive the C-type plate to move synchronously, so that the C-type plate will pull the two adjustment plates to move, so that the adjustment port on the adjustment plate will open larger holes on the mesh plate, so that the cold air in the air cooling box can blow more to the surface of the greenhouse film, so as to better cool the greenhouse film and avoid deformation of the high-temperature greenhouse film when it is rolled up.

[0032] When in use, the end of the produced greenhouse film is passed through two guide rollers 6, the temperature measuring roller 4 and the limiting roller 5 in turn and fixed on the winding drum 3. The support shaft 10 is driven to rotate by the driving motor 30, so that the support shaft 10 drives the extension shaft 7 to rotate through the two second conical wheels 12, the two first conical wheels 9 and the V-belt 13, so that the extension shaft 7 drives the winding shaft 2 to rotate, and the winding shaft 2 drives the winding drum 3 to roll and wind the greenhouse film.

[0034] When the greenhouse film passes through the temperature measuring roller 4, the heat of the processed greenhouse film will be transferred to the temperature measuring roller 4. When the heat carried by the greenhouse film is high, the temperature transferred to the temperature measuring roller 4 will increase accordingly, so that the increased temperature can be directly transferred to the mercury filled in the temperature measuring roller 4, so that the mercury expands due to the heat, and pushes the piston 19 outward, so that the guide rod 21 installed on the piston 19 can drive the inclined plate 23 to move accordingly, so that the inclined plate 23 drives the Z-shaped rod 15 fixedly installed therewith to move, so that the Z-shaped rod 15 can respectively drive the first conical wheel 9 and the second conical wheel 12 installed correspondingly to move through the first moving plate 8 and the second moving plate 11. Through the transmission installation of the synchronous gear 18 and the rack 16, the two Z-shaped rods 15 can be synchronously moved away from (or close to) each other, so as to simultaneously adjust the distance between the two first conical wheels 9 and the two second conical wheels 12, thereby realizing the transmission ratio between the support shaft 10 and the extension shaft 7. When it is detected that the temperature of the greenhouse film is too high, the rotation speed of the winding shaft 2 is reduced to avoid stretching or deformation caused by excessive winding speed of the greenhouse film, thereby ensuring that the greenhouse film maintains good shape and dimensional stability during the winding and winding process; when it is detected that the temperature of the greenhouse film is within the suitable winding temperature range, the rotation speed of the winding shaft 2 can be restored or accelerated to ensure the winding and winding efficiency of the greenhouse film and reduce the production cycle.

[0035] In this embodiment, a cooling mechanism is also installed between the two wall panels 1, and the cooling mechanism includes an air-cooling box 24 that is symmetrically fixedly installed between the two wall panels 1, and a three-way pipe 25 that is connected to each other is fixedly installed between the two air-cooling boxes 24. The three-way pipe 25 is connected to an external hair dryer, so that the wind blown by the external hair dryer can pass through the two air-cooling boxes 24 and blow to the upper and lower sides of the greenhouse film to cool the greenhouse film; the outer surface of the adjacent side of the air-cooling box 24 is an open structure, and a mesh plate 26 is fixedly installed on the inner wall of the opening, and an adjustment plate 27 is slidably installed inside the air-cooling box 24. The adjustment plate 27 is slidably installed on the outer surface of the mesh plate 26, and a plurality of adjustment openings 28 are evenly penetrated on the outer surface of the adjustment plate 27, and a C-shaped plate 29 is fixedly installed between the same end ends of the two telescopic adjustment plates 27 arranged upper and lower, and the C-shaped plate 29 is fixedly installed on the outer surface of the inclined plate 23.

[0036] When it is detected that the temperature of the greenhouse film is high, the inclined plate 23 moves outward and at the same time drives the C-shaped plate 29 to move synchronously, so that the C-shaped plate 29 pulls the two adjustment plates 27 to move, so that the adjustment port 28 on the adjustment plate 27 opens the larger holes on the mesh plate 26, so that the cold air in the air cooling box 24 can blow more toward the surface of the greenhouse film, so as to better cool the greenhouse film and avoid deformation of the greenhouse film with a higher temperature when it is rolled up.

[0037] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the end of the produced greenhouse film is sequentially passed through the two guide rollers 6, the temperature measuring roller 4 and the limiting roller 5 and fixed on the winding drum 3, and the support shaft 10 is driven to rotate by the driving motor 30, so that the support shaft 10 drives the extension shaft 7 to rotate through the two second conical wheels 12, the two first conical wheels 9 and the V-belt 13, so that the extension shaft 7 drives the winding shaft 2 to rotate, so that the winding shaft 2 drives the winding drum 3 to roll and wind the greenhouse film;

[0038] When the greenhouse film passes through the temperature measuring roller 4, the heat of the processed greenhouse film will be transferred to the temperature measuring roller 4. When the heat carried by the greenhouse film is high, the temperature transferred to the temperature measuring roller 4 will increase accordingly, so that the increased temperature can be directly transferred to the mercury filled in the temperature measuring roller 4, so that the mercury expands due to the heat, and pushes the piston 19 outward, so that the guide rod 21 installed on the piston 19 can drive the inclined plate 23 to move accordingly, so that the inclined plate 23 drives the Z-shaped rod 15 fixedly installed therewith to move, so that the Z-shaped rod 15 can respectively drive the first conical wheel 9 and the second conical wheel 12 installed correspondingly to move through the first moving plate 8 and the second moving plate 11. The two Z-shaped rods 15 can be synchronously moved away from (or close to) each other through the transmission installation of the synchronous gear 18 and the rack 16, so as to simultaneously adjust the distance between the two first conical wheels 9 and the two second conical wheels 12, thereby realizing the transmission ratio between the support shaft 10 and the extension shaft 7. When it is detected that the temperature of the greenhouse film is too high, the rotation speed of the winding shaft 2 is reduced to avoid the greenhouse film from being stretched or deformed due to excessive winding speed, thereby ensuring that the greenhouse film maintains good shape and dimensional stability during the winding and winding process; when it is detected that the greenhouse film temperature is within the suitable winding temperature range, the rotation speed of the winding shaft 2 can be restored or accelerated to ensure the winding and winding efficiency of the greenhouse film and reduce the production cycle;

[0039] When it is detected that the temperature of the greenhouse film is high, the inclined plate 23 moves outward and at the same time drives the C-shaped plate 29 to move synchronously, so that the C-shaped plate 29 pulls the two adjustment plates 27 to move, so that the adjustment port 28 on the adjustment plate 27 opens the larger holes on the mesh plate 26, so that the cold air in the air cooling box 24 can blow more toward the surface of the greenhouse film, so as to better cool the greenhouse film and avoid deformation of the greenhouse film with a higher temperature when it is rolled up.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
