Description

Technical Field

[0001] This utility model relates to the field of roller shutter machine technology, specifically a roller shutter machine. Background Technology

[0002] Plastic greenhouses have been widely used in rural areas, greatly promoting rural economic development. In order to suit the growth of crops in plastic greenhouses, the temperature and humidity inside the greenhouse need to be adjusted frequently. Therefore, in winter nights, some greenhouses often need to cover the greenhouse roof with insulation blankets to keep warm. During the day, the insulation blankets need to be rolled up to allow the greenhouse film to be exposed to sunlight for warmth. This is where the greenhouse curtain rolling machine, also known as a greenhouse curtain rolling machine, is used. It is an agricultural machinery device used for the automatic rolling up and down of greenhouse straw curtains.

[0003] Traditional rolling shutter machines can automatically roll up the insulation cloth, but the rolled-up insulation cloth is mostly placed directly on the top of the greenhouse, which makes the greenhouse have to bear a lot of weight. Over time, there is a risk that the greenhouse support rods will collapse. Therefore, we urgently need a roller-type rolling shutter machine. Utility Model Content

[0004] The purpose of this invention is to provide a roller-type rolling shutter machine to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a roller shutter machine, including a base, a shutter mechanism is provided on the top of the base, and an adjustment mechanism is provided on the outside of the shutter mechanism;

[0006] The roller shutter mechanism includes a rotating rod and a bracket. A first connecting block is fixedly connected to the outside of the rotating rod. A telescopic rod is fixedly connected to one end of the first connecting block. A second connecting block is fixedly connected to one end of the telescopic rod. A pulley is fixedly connected to one end of the second connecting block. A take-up roller is rotatably connected to one end of the second connecting block. A first servo motor is installed at one end of the take-up roller.

[0007] Preferably, there are two bases, and the two ends of the rotating rod are rotatably connected to one end of each of the two bases.

[0008] Preferably, the bracket is arc-shaped, and one end of the pulley is slidably connected to one end of the bracket.

[0009] Preferably, a second servo motor is installed at one end of the rotating rod, and one end of the first servo motor is fixedly connected to one end of the second connecting block.

[0010] Preferably, the adjustment mechanism includes a first fixed block and a second fixed block. One end of the first fixed block is fixedly connected to a threaded block, and one end of the first fixed block is rotatably connected to a movable ring. A slider is fixedly connected to the inner side of the movable ring.

[0011] Preferably, the second fixing block is fixedly connected to one end of the take-up roller, and one end of the second fixing block is provided with a threaded groove.

[0012] Preferably, multiple sliders are provided, and one end of each slider is slidably connected to one end of the take-up roller.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] First, this utility model involves installing two bases at opposite ends of the greenhouse, then bolting the bracket to the bases. A second servo motor is activated to rotate the rotating rod, which in turn rotates the external first connecting block, which in turn rotates the connected telescopic rod. Since the pulley is slidably connected to the inner side of the bracket, the second connecting block can move along the arc of the bracket. Simultaneously, the first servo motor is activated to rotate the winding roller, which in turn winds up the insulation cloth until it reaches the designated position, completing the winding operation. To unwind the insulation cloth, simply repeat the above steps, rotating the rod and winding roller in opposite directions. The bracket design allows the frame to bear the pressure of the rolled-up insulation cloth, preventing damage to the greenhouse frame.

[0015] Secondly, this utility model sets up multiple take-up rollers, with two take-up rollers rotatably connected to one end of two second connecting blocks respectively. When it is necessary to adjust the length of the take-up rollers according to the length of the greenhouse, simply pull the moving ring to make the slider slide on the take-up rollers, so that the second fixing block at one end of one take-up roller approaches the first fixing block at one end of another take-up roller until the threaded block at one end of the first fixing block contacts the threaded groove at one end of the second fixing block. Then, rotate the first fixing block to make the threaded block rotate into the threaded groove of the second fixing block, thus completing the connection of the two take-up rollers. Repeating the above operation can complete the connection of multiple take-up rollers, achieving the effect of conveniently adjusting the length of the take-up rollers as needed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] This utility model provides the following technical solution: Example

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A roller shutter machine includes a base 1, a shutter mechanism 2 is provided on the top of the base 1, and an adjustment mechanism 3 is provided on the outside of the shutter mechanism 2.

[0024] The roller shutter mechanism 2 includes a rotating rod 21 and a bracket 22. A first connecting block 23 is fixedly connected to the outside of the rotating rod 21. A telescopic rod 24 is fixedly connected to one end of the first connecting block 23. A second connecting block 25 is fixedly connected to one end of the telescopic rod 24. A pulley 26 is fixedly connected to one end of the second connecting block 25. A take-up roller 27 is rotatably connected to one end of the second connecting block 25. A first servo motor 28 is installed at one end of the take-up roller 27.

[0025] There are two bases 1, and the two ends of the rotating rod 21 are rotatably connected to one end of each of the two bases 1.

[0026] The bracket 22 is arc-shaped, and one end of the pulley 26 is slidably connected to one end of the bracket 22.

[0027] A second servo motor is installed at one end of the rotating rod 21, and one end of the first servo motor 28 is fixedly connected to one end of the second connecting block 25.

[0028] Through the above technical solution, two bases 1 are installed at both ends of the greenhouse, and the bracket 22 is bolted to the base 1. Then, the second servo motor is started to drive the rotating rod 21 to rotate, thereby driving the first connecting block 23 outside it to rotate, and then driving the telescopic rod 24 connected to it to rotate. Since the pulley 26 is slidably connected to the inner side of the bracket 22, the second connecting block 25 can be driven to move along the arc line of the bracket 22. When the second connecting block 25 moves, the first servo motor 28 is started to drive the winding roller 27 to rotate, thereby driving the winding roller 27 to wind up the insulation cloth until the telescopic rod 24 reaches the designated position, completing the winding operation of the insulation cloth. When it is necessary to lower the insulation cloth, simply repeat the above steps to make the rotating rod 21 and the winding roller 27 rotate in opposite directions. The bracket 22 is designed so that after the insulation cloth is wound up, the bracket 22 can bear the pressure of the insulation cloth, avoiding damage to the greenhouse frame. Example

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the adjustment mechanism 3 includes a first fixed block 31 and a second fixed block 32. One end of the first fixed block 31 is fixedly connected to a threaded block 33, and one end of the first fixed block 31 is rotatably connected to a moving ring 34. A slider 35 is fixedly connected to the inner side of the moving ring 34.

[0030] The second fixing block 32 is fixedly connected to one end of the take-up roller 27, and a threaded groove is provided on one end of the second fixing block 32.

[0031] Multiple sliders 35 are provided, and one end of each slider 35 is slidably connected to one end of the take-up roller 27.

[0032] Through the above technical solution, by setting multiple take-up rollers 27, two of which are rotatably connected to one end of two second connecting blocks 25 respectively, when it is necessary to adjust the length of the take-up rollers 27 according to the length of the greenhouse, simply pull the moving ring 34 to make the slider 35 slide on the take-up rollers 27, so that the second fixing block 32 at one end of one take-up roller 27 approaches the first fixing block 31 at one end of the other take-up roller 27 until the threaded block 33 at one end of the first fixing block 31 contacts the threaded groove at one end of the second fixing block 32. Then, rotate the first fixing block 31 so that the threaded block 33 rotates into the threaded groove of the second fixing block 32, thus completing the connection of the two take-up rollers 27. By repeating the above operation, multiple take-up rollers 27 can be connected, achieving the effect of conveniently adjusting the length of the take-up rollers 27 as needed.
