Description

Technical Field

[0001] This utility model relates to the field of automatic greenhouse film rolling equipment, and in particular to a waterproof electric film rolling machine. Background Technology

[0002] With the development of agricultural production, greenhouses have been widely used. Crops grow inside greenhouses, so the temperature and humidity inside need to be regulated regularly. Therefore, the greenhouse film needs to be rolled up or closed in a timely manner to ensure that the temperature inside the greenhouse is suitable for crop growth. Greenhouse technology can also be applied to animal husbandry and livestock farming.

[0003] Chinese utility model patent 201320543510.4 discloses a waterproof electric film winding machine, including a motor mounting base. A motor is mounted on one side of the motor mounting base, and a reducer is connected to the other side of the motor mounting base. The motor outputs torque to the reducer. A film winding shaft with external torque output is provided on the reducer. An outer cover is mounted on one side of the motor mounting base. A stroke adjustment mechanism is installed in the cavity formed by the motor mounting base and the outer cover. A flip-top waterproof cover is provided on the outer cover. Although the waterproof cover can effectively prevent rainwater from entering, when the user forgets to close the waterproof cover, rainwater will enter the cavity through the hole on the outer cover, which will cause damage to the components inside the cavity. In addition, the existing output shaft and the connecting sleeve of the film winding tube are all hinged by a pin. Under long-term operation, the pin is prone to severe wear or even breakage, reducing the reliability of the entire machine. Summary of the Invention

[0004] This utility model provides a waterproof electric film rolling machine. Even if the waterproof cover is left on, it can prevent rainwater and dust from entering the chamber, thus improving its service life. The perfect combination of the output shaft and the connecting sleeve, secured by set screws, enhances operational reliability. The specific solution is as follows: A waterproof electric film rolling machine includes a motor mounting base, a motor mounted on one side of the mounting base, and a reducer mounted on the other side of the mounting base. The motor outputs torque to the reducer, and the reducer has an output shaft that outputs torque externally. A waterproof cover is mounted on one side of the mounting base. A stroke adjustment mechanism is installed in the cavity formed by the outer cover and the motor mounting base. The stroke adjustment mechanism is characterized in that both the first and second adjusting gears of the stroke adjustment mechanism have sealing rings on their adjusting shafts. One end of the sealing ring abuts against a support plate, and the other end abuts against an annular groove in the outer cover to prevent rainwater from entering the cavity through the hole in the outer cover when the waterproof cover is left open. One side of the outer wall of the output shaft is flat, and one end of a connecting sleeve has a mounting hole adapted to the output shaft. The output shaft is inserted into the connecting sleeve and fixed by a set screw.

[0005] Furthermore, one end of the connecting sleeve is provided with an output shaft mounting hole for inserting the output shaft, and the other end of the connecting sleeve is provided with a film winding tube mounting hole for inserting the film winding tube. The inner cavity of the connecting sleeve has a partition plate in the middle, which divides the internal space of the connecting sleeve so that the two mounting holes of the connecting sleeve are not connected to each other, so as to prevent rainwater from impacting the reducer from the film winding tube mounting hole and entering the reducer.

[0006] Furthermore, the inner surface of the outer cover has an annular outer edge near the hole, and the sealing ring is fitted onto the adjusting shaft. After the outer cover is installed, the sealing ring is pressed into the annular groove of the annular outer edge.

[0007] Furthermore, the stroke adjustment mechanism includes a transmission gear assembly, a first adjusting gear disc, a second adjusting gear disc, a first limit switch, a second limit switch, and a circuit board. The first and second adjusting gear discs are rotatably mounted on the support of the chamber. A support plate is set on the outside of the first and second adjusting gear discs. The motor outputs torque to the transmission gear assembly. The output gears of the transmission gear assembly mesh with the lower peripheral teeth of the first and second adjusting gear discs respectively. A pawl is provided on one side of the upper part of both the first and second adjusting gear discs. The first and second limit switches respectively cooperate with the corresponding pawls. The first and second limit switches are connected to the circuit board wires, and the circuit board controls the motor's movement.

[0008] Furthermore, the reducer housing and the motor mounting base are integrally formed.

[0009] Furthermore, a sealing gasket is provided between the motor mounting base and the outer cover to ensure a sealed connection between the motor mounting base and the outer cover.

[0010] This utility model features a simple structure and reasonable design. By adding a sealing ring to the adjusting shaft of the adjusting gear plate, it prevents rainwater and dust from seeping into the cavity through the holes in the outer cover, ensuring that the components inside the cavity are not damaged. This improves the waterproof performance of the electric film winding machine and extends its service life. The perfect fit between the output shaft and the mounting hole at one end of the connecting sleeve, along with the fixing with a set screw, enhances operational reliability.

[0013] like Figures 1-4 As shown, the waterproof electric film rolling machine of this utility model includes a motor mounting base 1, a motor 2 mounted on one side of the motor mounting base 1, and a reducer 3 mounted on the other side of the motor mounting base 1. The housing of the reducer 3 is integrally formed with the motor mounting base 1. The motor 2 outputs torque to the reducer 3. The reducer 3 is provided with an output shaft 31 that outputs torque externally. The output shaft 31 is connected to an external film rolling tube through a connecting sleeve 4. An outer cover 6 is provided on one side of the motor mounting base 4, and a waterproof cover 61 is provided on the outer cover 6. A stroke adjustment mechanism is provided in the cavity formed by the motor mounting base 4 and the outer cover 6. The stroke adjustment mechanism includes a transmission gear assembly 71, a first adjusting gear 73, a second adjusting gear 74, a first limit switch 75, a second limit switch 76, and a circuit board. The first adjusting gear 73 and the second adjusting gear 74 are rotatably mounted in the cavity. The motor 1 outputs torque to the transmission gear assembly 71. The output gears of the transmission gear assembly 71 mesh with the lower circumferential teeth of the first adjusting gear 73 and the second adjusting gear 74, respectively. A pawl is provided on one side of the upper part of the first adjusting gear 73 and the second adjusting gear 74.

[0016] One end of the connecting sleeve 4 is provided with an output shaft mounting hole 41 for the output shaft 31 to be inserted, and the other end of the connecting sleeve 4 is provided with a film winding tube mounting hole for the film winding tube to be inserted. The inner cavity of the connecting sleeve 4 has a partition plate in the middle, which divides the internal space of the connecting sleeve 4 so that the two mounting holes of the connecting sleeve 4 are not connected to each other, so as to prevent rainwater from impacting the reducer from the film winding tube mounting hole and entering the reducer.

[0017] The outer cover 6 has an annular outer edge 63 near the hole 62. The sealing ring 8 is fitted on the first adjusting shaft 731 and the second adjusting shaft 741. After the outer cover 6 is installed, the sealing ring 8 is pressed into the annular groove 64 of the annular outer edge 63.

[0018] Both the outer cover 6 and the support plate 7 are made of transparent material. The outer surface of the outer cover 6 is provided with graduated rings corresponding to the first adjusting gear plate 73 and the second adjusting gear plate 74.
