Description

Technical Field

[0001] This utility model relates to the field of film feeding and discharging devices, and in particular to a film discharging support. Background Technology

[0002] With the development of agricultural production, the application of greenhouses has become more and more widespread. They are now widely used in the cultivation of Chinese medicinal herbs, crops, fruits and flowers. Due to seasonal factors or the need for inspection and maintenance of greenhouse films, it is necessary to manually pull out the plastic film from the roll and then cover the greenhouse frame with the pulled-out plastic film.

[0003] A search revealed a Chinese patent application with patent number CN201720953865.9, which discloses a multifunctional greenhouse film loading and unloading device. The device uses a clamping device to drive the first movable groove to move, and uses casters to facilitate the movement of the device, making it easy to install and replace the roll. It can continuously load and unload the film, reducing manual labor. However, the above-mentioned technical solution has multiple mechanisms such as motors and storage compartments in the overall receiving and releasing device, resulting in a large overall structure and heavy weight. Therefore, it is inconvenient to move and use it in muddy and pitted fields. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a membrane placement support.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A film placement support includes a set of V-shaped legs. Fixing plates are fixed to the outer walls of opposite sides of the V-shaped legs. The outer walls of the fixing plates have slots. A rotating rod is inserted into the inner wall of the slot. A sleeve is sleeved on the outer wall of the rotating rod. A roll of film is sleeved on the outer wall of the sleeve.

[0006] As a further improvement of this utility model: a set of first support shafts is fixed to the top outer wall of the fixing plate, and a set of second support shafts is fixed to the inner walls on both sides of the slot.

[0007] As a further embodiment of this utility model: a set of rollers is rotatably connected to the outer walls of the second support shaft and the first support shaft, and the rollers are located on both sides of the fixed plate.

[0008] As a further improvement of this utility model, the first support shaft and the second support shaft are respectively connected to limit nuts by threaded connections at both ends.

[0009] As a further improvement of this utility model: a set of limiting plates are fixed to the outer wall of the fixing plate, and the outer walls of the limiting plates are respectively fixed to the outer walls of the two sides of the V-shaped support leg.

[0010] As a further improvement of this utility model: a set of first reinforcing rods is fixed to the outer wall of the opposite side of the V-shaped support leg, and a second reinforcing rod is fixed to the inner wall of the opposite side of the V-shaped support leg.

[0011] The beneficial effects of this utility model are as follows: 1. This film-laying support structure is simple and lightweight, allowing workers to easily place the support at various locations in the field. Then, the sleeve and film roll are placed on the outer wall of the rotating rod, and the rotating rod is placed on the inner wall of the fixed plate. Multiple sets of rollers on the outer walls of the first and second support shafts clamp and guide both ends of the rotating rod, improving the stability of the rotating rod when it rotates and lays the film outward, thus increasing the film-laying efficiency.

[0012] 2. Two sets of rollers located on both sides of the slot, supported by the first and second support shafts, guide and support the rotating rod inserted into the slot. This allows the rotating rod to rotate along with the continuously expanding film roll as the worker pulls out the plastic film, enabling the worker to quickly remove the plastic film. Once the film roll on the outer wall of the sleeve is completely removed, the worker only needs to pull the rotating rod placed on the inner wall of the fixing plate upwards to quickly replace the sleeve and film roll, thereby improving the efficiency of plastic greenhouse film covering.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0019] Example 1: A membrane placement stent, such as Figure 1-3 As shown, it includes a set of V-shaped support legs 1. The outer walls of the V-shaped support legs 1 on opposite sides are respectively fixed with fixing plates 2. The outer walls of the fixing plates 2 have slots 12. The inner walls of the slots 12 are inserted with rotating rods 3. The outer walls of the rotating rods 3 are sleeved with sleeves 7. The outer walls of the sleeves 7 are sleeved with membrane rolls 4. A set of first support shafts 8 are fixed to the top outer wall of the fixing plate 2, and a set of second support shafts 10 are fixed to the inner walls on both sides of the slot 12. The outer walls of the second support shaft 10 and the first support shaft 8 are respectively rotatably connected to a set of rollers 9, which are located on both sides of the fixed plate 2. Limit nuts are threadedly connected to both ends of the first support shaft 8 and the second support shaft 10. A set of limiting plates 11 are fixed to the outer wall of the fixing plate 2, and the outer walls of the limiting plates 11 are respectively fixed to the outer walls of the two sides of the V-shaped support leg 1.

[0020] A set of first reinforcing rods 5 are fixed to the outer wall of the opposite side of the V-shaped support leg 1, and a second reinforcing rod 6 is fixed to the inner wall of the opposite side of the V-shaped support leg 1. First, the frame structure consisting of V-shaped support legs 1 and first reinforcing rod 5 is placed on one side of the greenhouse support that needs to be covered with plastic film. Then, the sleeve 7 and film roll 4 to be placed on the outer wall of the rotating rod 3 are fitted. Then, the rotating rod 3 is placed on the two fixing plates 2 fixed at the top of the V-shaped support legs 1. The rotating rod 3 is supported and clamped by the slot 12 at the top of the fixing plate 2. The two sets of rollers 9 on both sides of the slot 12, supported by the first support shaft 8 and the second support shaft 10, can guide and support the rotating rod 3 inserted into the slot 12. When the workers pull out the plastic film of the film roll 4, the rotating rod 3 can rotate with the film roll 4 that is continuously being released outward, so that the workers can quickly pull out the plastic film. When the film roll 4 on the outer wall of the sleeve 7 is completely pulled out, the workers only need to pull the rotating rod 3 placed on the inner wall of the fixing plate 2 upward to quickly replace the sleeve 7 and film roll 4, thereby improving the efficiency of plastic greenhouse covering. Meanwhile, the structure of this film-laying support is simple and lightweight, allowing workers to easily place the support in various locations in the field. Then, the sleeve 7 and the film roll 4 are placed on the outer wall of the rotating rod 3, and the rotating rod 3 is placed on the inner wall of the fixing plate 2. Multiple sets of rollers 9 on the outer walls of the first support shaft 8 and the second support shaft 10 clamp and guide both ends of the rotating rod 3, improving the stability of the rotating rod 3 when it rotates and lays the film outward, thus improving the film-laying efficiency.

[0021] The fixing plate 2 is supported and reinforced by the limiting plate 11, so that the V-shaped support leg 1 can stably support the fixing plate 2. At the same time, the second reinforcing rod 6 and the first reinforcing rod 5 can improve the stability of the bracket structure composed of the V-shaped support leg 1.

[0022] Working principle: The frame structure consisting of V-shaped support legs 1 and first reinforcing rod 5 is placed on one side of the greenhouse support that needs to be covered with plastic film. Then, the sleeve 7 and film roll 4 to be placed on the outer wall of the rotating rod 3 are fitted. The rotating rod 3 is then placed on the two fixing plates 2 fixed at the top of the V-shaped support legs 1. The rotating rod 3 is supported and clamped by the slots 12 at the top of the fixing plates 2. The two sets of rollers 9 on both sides of the slots 12, supported by the first support shaft 8 and the second support shaft 10, can guide and support the rotating rod 3 inserted into the slots 12. When the worker pulls out the plastic film of the film roll 4, the rotating rod 3 can rotate with the film roll 4 that is continuously being released outward, allowing the worker to quickly pull out the plastic film. When the film roll 4 on the outer wall of the sleeve 7 is completely removed, the worker only needs to pull the rotating rod 3 placed on the inner wall of the fixing plate 2 upward to quickly replace the sleeve 7 and the film roll 4.
