Description
Technical Field
[0001] This utility model relates to the field of agricultural facilities technology, and in particular to a greenhouse insulation blanket rolling and unrolling anti-jamming limiting pulley system. Background Technology
[0002] Greenhouse insulation blankets are a new type of covering and insulation material specifically designed for greenhouses. They are used for insulation and cold protection in greenhouses at night or in low-temperature environments. They are composed of multiple layers of functional materials and have excellent thermal insulation, waterproofing, moisture resistance, and anti-aging properties. They reduce heat radiation and convection from inside the greenhouse through physical insulation, reducing energy consumption for coal or electric heating. The surface is covered with a waterproof coating, so it does not absorb water or increase weight in rainy or snowy weather, preventing the greenhouse frame from collapsing. It also prevents the internal filling material from rotting. It can be quickly opened and closed using manual or automated rolling equipment.
[0003] The greenhouse electric rolling shutter machine is a mechanized power device specifically designed for greenhouse insulation blankets. It uses a motor-driven transmission device to rotate the roller, automatically rolling up and down the insulation blanket. This machine replaces the traditional manual rolling method, significantly improving greenhouse management efficiency and reducing labor intensity. However, while achieving automatic rolling up and down of the insulation blanket, the greenhouse electric rolling shutter machine still suffers from structural defects, such as poor support structure stability. This can lead to roller shaft misalignment or even blanket jamming, requiring frequent manual correction. Current solutions employ a double-track constraint anti-misalignment design, adding upper and lower sliding rails to wrap around the roller shaft rollers, forcing the rollers to run along a predetermined path. However, this still suffers from instability and can cause misalignment and jamming. When jamming occurs, the impact increases, leading to high peak loads on the motor and potential overload burnout.

[0018] Reference Figure 4 , Figure 5 and Figure 6 An embodiment of this utility model provides a greenhouse insulation blanket rolling anti-jamming limiting pulley group, including a drive column 1, a mounting plate 2, and a belt 10.

The outer wall is smooth to reduce friction. The outer wall of the rotating column 704 is rotatably connected to the inner shaft 705. The inner shaft 705 serves as a lubricating part between the rotating column 704 and the fixed pulley 706, reducing friction loss. The outer wall of the inner shaft 705 is rotatably connected to the fixed pulley 706, which changes the direction of force transmission.

Specifically, the rotating motor 701 provides rotational force when energized, driving the drive wheel 702 to rotate and generate power.

[0020] Reference Figure 1 , Figure 2 and Figure 6The deceleration mechanism 8 includes two disc spring groups 801. The two disc spring groups 801 are fixedly connected to adjacent sides of mounting plate 1 2 and mounting plate 2 3 on opposite sides. The disc spring groups 801 can generate elastic force when they encounter pressure, which plays a buffering role. The two disc spring groups 801 are fixedly connected to adjacent sides of each other with a deceleration baffle 802. The deceleration baffle 802 is in direct contact with the movable pulley 602, generating force to decelerate the drive column 1. The outer walls of the two deceleration baffles 802 are provided with wheel grooves 803. The wheel grooves 803 increase the contact area of the deceleration baffles 802 and avoid stress concentration that causes wear. The lubrication mechanism 9 includes two lubricating oil tanks 901. The bottom ends of the two lubricating oil tanks 901 are fixedly connected to the top of the drive column 1. The lubricating oil tanks 901 can slowly produce lubricating oil. An oil groove 902 is opened on the top of the drive column 1. The lubricating oil from the lubricating oil tanks 901 flows through the oil groove 902 to the inner shaft 1 601 and the inner shaft 2 604 to increase lubrication and further reduce friction. The top of the upper support column 4 is provided with a support groove 11, and the top of the lower support column 5 is provided with a support groove 12. Both the support groove 11 and the support groove 12 restrict the deviation of the belt 10 and increase the tension. The outer wall of the mounting plate 2 3 is provided with a slot 13, which allows the belt 10 to pass through so as not to affect the movement. The top of the mounting plate 2 is fixedly connected with a detector 14, which is used to detect the operation of the drive wheel 702. The top of the upper support column 4 is fixedly connected with a speed detector 15, which is used to monitor the running speed of the belt 10. Specifically, the disc spring assembly 801 generates elastic force when subjected to pressure, thus providing a buffering effect. A deceleration baffle 802 is fixedly connected to each adjacent side of the two disc spring assemblies 801. The deceleration baffle 802 directly contacts the movable pulley 602, generating a force to decelerate the drive column 1. The wheel groove 803 expands the contact area of the deceleration baffle 802, preventing stress concentration and wear. The lubricating oil tank 901 slowly generates lubricating oil, which flows through the oil groove 902 to the inner shaft 1 601 and inner shaft 2 604, increasing lubrication and further reducing friction. Support groove 11 and support groove 2 12 both restrict the offset of the belt 10 and increase tension. The slot 13 allows the belt 10 to pass through to avoid affecting movement. The detector 14 is used to detect the operation of the drive pulley 702, and the speed sensor 15 is used to monitor the running speed of the belt 10.
[0021] Working principle: When the moving mechanism 6 starts to move, the inner shaft 601 acts as a lubricating part between the movable pulley 602 and the drive column 1, reducing friction loss and avoiding offset caused by rotation. The wheel groove 603 has a large friction surface, and the belt 10 drives the whole movement by generating friction with the wheel groove 603. The inner shaft 604 also acts as a lubricating part between the slide rail wheel 605 and the drive column 1, reducing friction loss. The upper slide groove 606 and the lower slide groove 607 form a double slide rail, which wraps around the slide rail wheel 605. 05. It can rotate freely in the slide rail to prevent vertical and left and right deviations. The end of the belt 10 is connected to the fixed block 608. When the belt 10 moves, the fixed block 608 generates tension. The bottom of the T-shaped column 6091 is fixedly connected to the outer wall of the drive column 1. The T-shaped column 6091 ensures that the drive column 1 runs on the specified track and avoids shaking. The slide rail groove 6092 and the inner groove 6093 have smooth inner walls to reduce friction loss, prevent deviation, and reduce wear and jamming caused by friction. Furthermore, the overall operation requires the rotational motor 701 to provide rotational force. The rotational motor 701 drives the drive wheel 702 to rotate and generate power. The starting end of the belt 10 is on the second groove 703. The rotation of the drive wheel 702 tightens the belt 10 and generates transmission. The rotating column 704 provides support, and its smooth outer wall reduces friction. The inner shaft 705 serves as a lubricating part between the rotating column 704 and the fixed pulley 706, reducing friction loss. The fixed pulley 706 changes the direction of force transmission. The outer wall of the third groove 707 is in close contact with the belt 10, driving the fixed pulley 706 to rotate. The support assembly 708 is mainly used to support the drive wheel 702. The right side of the fixing plate 7081 is fixedly connected to the support column 7082. The fixing plate 7081 and the support column 7082 are used to fix the drive wheel 702, ensuring that the drive wheel 702 does not detach, reducing friction, improving operating efficiency, and avoiding jamming.
