Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse film installation, in particular to a greenhouse film clamping groove and a greenhouse. Background Art

[0002] At present, the greenhouse film slot is one of the main accessories for greenhouse film fixing, which is used to firmly fix the film of the greenhouse. For example, the thin greenhouse film in the greenhouse in agriculture and animal husbandry is fixed. There are many types of greenhouse film slots, including single spring slots, double spring slots, three spring slots and press-in slots. The design of the greenhouse film slot uses reasonable inner angles and self-locking functions, so that the film can be used firmly in the greenhouse even in the windy season. Choosing a suitable greenhouse film slot can greatly improve the stability of the film in the greenhouse, thereby helping to improve the growth environment of crops.

[0003] During use, the direct contact between the greenhouse film slot and the greenhouse film increases the wear of the greenhouse film; in summer, the greenhouse film is scalded and softened by the high temperature of the metal surface of the greenhouse film slot, so that the thin greenhouse film forms two thin and long scalded and softened bands along the slot direction, reducing the toughness and tensile strength of the greenhouse film, and cracking early. This means that the life of the greenhouse film is greatly reduced and the operating cost of the greenhouse increases significantly. Utility Model Content

[0044] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] In the description of the embodiments of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0046] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0047] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model embodiment. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0048] Combine the following Figures 1 to 18 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute a limitation on the present invention.

[0049] like Figures 1 to 12 As shown, the utility model provides a greenhouse film slot 100, comprising: a reflective coating 101, and the reflective coating 101 is arranged on at least a part of the contact portion between the greenhouse film slot 100 and the greenhouse film 200. The reflective coating 101 can be a coating of uniform thickness or a coating of non-uniform thickness.

[0050] During the high temperature in summer, when the metal surface temperature of the greenhouse film slot 100 reaches above 60°C, the greenhouse film 200 is partially deformed and softened. The installation of the greenhouse film 200 has a pre-tension force, which makes the greenhouse film 200 easily stretched or torn, shortening the life of the greenhouse film 200, and thus shortening the life of the greenhouse. Furthermore, during the operation of the greenhouse, the greenhouse film 200 is impacted by the internal and external air, and the greenhouse film 200 will flutter and cause micro-friction with the edge of the greenhouse film slot 100. The micro-friction never stops, making it easy for the greenhouse film 200 to be worn into a long strip of wear and tear by the edge of the greenhouse film slot 100, shortening the life of the greenhouse film 200, and shortening the life of the greenhouse. The reflective coating 101 isolates the direct contact between the slot and the greenhouse film 200. The reflective coating 101 has the function of reflecting and isolating heat, reducing the local temperature rise of the greenhouse film slot 100, reducing the wear, high temperature burns, and softening of the greenhouse film 200, and greatly improving the overall life of the greenhouse film 200.

[0051] like Figures 1 to 8 As shown, in one embodiment of the present invention, the greenhouse film slot 100 includes: a first slot edge 110 and a second slot edge 120, the first slot edge 110 and the second slot edge 120 relatively form a slot, and the first slot edge 110 and the second slot edge 120 are both in contact with the greenhouse film 200; wherein, at least one side of the first slot edge 110 and the second slot edge 120 is provided with a reflective coating 101.

[0052] Specifically, the first groove edge 110 and the second groove edge 120 of the greenhouse film slot 100 are arranged in parallel, and the first groove edge 110 and the second groove edge 120 extend along the length direction of the greenhouse film slot 100. The greenhouse film 200 is placed in the greenhouse film slot 100, and passes through the greenhouse film slot 100 from the first groove edge 110 and the second groove edge 120. During the process of passing in and out, the greenhouse film 200 contacts the first groove edge 110 and the second groove edge 120.

[0053] For example, Figure 2 and Figure 3 As shown, a reflective coating 101 is provided on one side of the first groove edge 110 and the second groove edge 120. Alternatively, as Figures 4 to 8 As shown, a reflective coating 101 is disposed on both the first groove edge 110 and the second groove edge 120 .

[0054] like Figure 2 and Figure 3As shown, in a specific embodiment of the present invention, the cross section of the first groove edge 110 includes a first straight segment 111, a first arc segment 112, and a second straight segment 113 connected in sequence, and the first straight segment 111 and the second straight segment 113 are arranged opposite to each other; for example, the first straight segment 111 and the second straight segment 113 are arranged in parallel. The cross section of the second groove edge 120 includes a third straight segment 121, a second arc segment 122, and a fourth straight segment 123 connected in sequence, and the third straight segment 121 and the fourth straight segment 123 are arranged opposite to each other, and the third straight segment 121 and the fourth straight segment 123 are arranged in parallel. The first arc segment 112 and the second arc segment 122 are arranged opposite to each other; wherein, at least one of the first straight segment 111, the first arc segment 112, the second straight segment 113, the third straight segment 121, the second arc segment 122, and the fourth straight segment 123 is provided with a reflective coating 101.

[0055] For example, the first groove edge 110 and the second groove edge 120 are bent structures, and the ends are bent to the inside of the greenhouse film slot 100, and the bent ends of the first groove edge 110 and the bent ends of the second groove edge 120 face oppositely; thereby making the contact between the greenhouse film 200 and the greenhouse film slot 100 relatively smooth, thereby preventing damage to the greenhouse film 200. Specifically, the first straight line segment 111 and the third straight line segment 121 face the inside of the greenhouse film slot 100, for example, the first straight line segment 111 and the second straight line segment 113 can be collinear.

[0056] In addition, for example, the reflective coating 101 is provided on the first groove edge 110, the reflective coating 101 can be provided on the first straight segment 111, or the reflective coating 101 is provided on the second straight segment 113, or the reflective coating 101 is provided on the first arc segment 112. The reflective coating 101 can be provided on the first straight segment 111 and the first arc segment 112, or on the first arc segment 112 and the second straight segment 113. Figure 3 As shown, the reflective coating 101 may be provided on the first straight segment 111 , the second straight segment 113 , and the first arc segment 112 .

[0057] In addition, a reflective coating 101 is provided on the second groove edge 120, and a reflective coating 101 can be provided on the third straight segment 121, or a reflective coating 101 can be provided on the fourth straight segment 123, or a reflective coating can be provided on the second arc segment 122. Figure 2 As shown, the reflective coating 101 is disposed on the fourth straight segment 123 and the second arc segment 122. The reflective coating 101 may be disposed on the third straight segment 121, the second arc segment 122, and the fourth straight segment 123.

[0058] Furthermore, if Figures 4 to 8As shown, a reflective coating 101 is disposed on both the first groove edge 110 and the second groove edge 120. Figure 4 As shown, in one embodiment of the present invention, a reflective coating 101 is provided on the first arc segment 112 of the first groove edge 110 and the second arc segment 122 of the second groove edge 120. Figure 5 As shown, the first straight line segment 111 and the first arc segment 112 of the first groove edge 110 are provided with a reflective coating 101; the third straight line segment 121 and the second arc segment 122 of the second groove edge 120 are provided with a reflective coating 101. Figure 6 As shown, the third straight line segment 121 and the first arc segment 112 of the first groove edge 110 are provided with a reflective coating 101; the fourth straight line segment 123 and the second arc segment 122 of the second groove edge 120 are provided with a reflective coating 101. Figure 7 As shown, the first straight segment 111 and the first arc segment 112 of the first groove edge 110 are provided with a reflective coating 101 , and the second arc segment 122 and the fourth straight segment 123 of the second groove edge 120 are provided with a reflective coating.

[0059] like Figure 8 As shown, in another optional embodiment of the utility model, the first straight segment 111, the first arc segment 112 and the second straight segment 113 of the first groove edge 110 are provided with a reflective coating 101; the third straight segment 121, the second arc segment 122 and the fourth straight segment 123 of the second groove edge 120 are provided with a reflective coating 101. The reflective coating 101 completely covers the first groove edge 110 and the second groove edge 120, so as to better isolate the greenhouse film 200 from the position where the pre-tightening force of the greenhouse film clamping groove 100 is large, and the first groove edge 110 and the second groove edge 120 receive more light and the temperature rises faster. The reflective coating 101 is provided here, which is more conducive to the protection of the greenhouse film 200.

[0060] like Figures 9 to 12 As shown, in other embodiments of the present invention, the greenhouse film slot 100 further includes a first extension portion 130, a second extension portion 140 and a bottom portion 150, the first extension portion 130 is connected between the first slot edge 110 and the bottom portion 150, and the second extension portion 140 is connected between the second slot edge 120 and the bottom portion 150; the first extension portion 130, the second extension portion 140 and the bottom portion 150 form the inner wall of the slot, and the inner wall of the slot is provided with a reflective coating 101. Specifically, the inner wall of the first extension portion 130, the second extension portion 140 and the bottom portion 150 forms the inner wall of the slot, and the inner wall of the slot is in contact with the greenhouse film 200, and the reflective coating 101 is provided on the inner wall of the slot to prevent friction.

[0061] Among them, the first extension part 130, the second extension part 140, the bottom 150, the first groove edge 110 and the second groove edge 120 can be an integral structure, and the groove shape is formed by bending. The greenhouse film slot 100 is a symmetrical structure, symmetrical along the midline of the bottom 150. For example, the first extension part 130 and the second extension part 140 can be a straight plate structure, or have a certain curvature. The first extension part 130, the second extension part 140 and the bottom 150 are U-shaped, and the first groove edge 110 and the second groove edge 120 are arranged at the opening of the U-shape and are retracted inwardly. For example, the distance between the first groove edge 110 and the second groove edge 120 is less than the length of the bottom 150; the first extension part 130 and the second extension part 140 are equal in length.

[0062] like Fig.10 As shown, a continuous reflective coating 101 is provided on the inner wall of the groove, the first groove edge 110 and the second groove edge 120 .

[0063] Of course, if Fig.11 As shown, the inner wall and the outer wall of the greenhouse film slot 100 as well as the first slot edge 110 and the second slot edge 120 can be provided with a reflective coating 101 , which is equivalent to wrapping the entire greenhouse film slot 100 with the reflective coating 101 .

[0064] For example, Fig. 9 As shown, a reflective coating 101 may be provided inside and outside the first extension portion 130 , the second extension portion 140 , and the first groove edge 110 and the second groove edge 120 .

[0065] like Figures 10 to 12 As shown, in some optional embodiments of the present invention, the connection between the first extension portion 130 and the bottom 150 is a first arc portion 131, and the connection between the second extension portion 140 and the bottom 150 is a second arc portion 141. The first arc portion 131 and the second arc portion 141 are in contact with the greenhouse film 200, and the inner wall of at least one of the first arc portion 131 and the second arc portion 141 is provided with a reflective coating 101.

[0066] In other words, the reflective coating 101 is disposed on the first arc portion 131 of the first extension portion 130 , or the reflective coating 101 is disposed on the second arc portion 141 of the second extension portion 140 , or the reflective coating 101 is disposed on both the first arc portion 131 and the second arc portion 141 .

[0067] For example, Fig.12As shown, the reflective coating 101 is arranged on the first arc portion 131, the second arc portion 141, the first groove edge 110 and the second groove edge 120. The greenhouse film 200 is first placed in the greenhouse film slot 100, and then a clamping spring 210 is arranged on the greenhouse film 200. The clamping spring 210 is clamped on the first arc portion 131 and the second arc portion 141. After the greenhouse film 200 is tightened, it contacts the first groove edge 110 and the second groove edge 120. That is to say, after the greenhouse film 200 is installed, it mainly contacts the greenhouse film slot 100 at the first arc portion 131, the second arc portion 141, the first groove edge 110 and the second groove edge 120, which is easy to cause damage to the greenhouse film 200. Therefore, the reflective coating 101 is arranged at the above-mentioned positions.

[0068] Specifically, in other embodiments of the present invention, the reflective coating 101 can be made of one or more highly reflective coatings selected from the group consisting of polyethylene (PE), polyethylene terephthalate (PET), ethylene-vinyl acetate copolymer (EVA), polypropylene (PP), polyvinyl chloride (PVC), epoxy resin, and acrylic acid.

[0069] Further, in the embodiment of the present invention, the thickness of the reflective coating 101 is less than or equal to 2 mm. For example, in the area where the reflective coating 101 is provided in the greenhouse film slot 100, the thickness of the reflective coating 101 may be equal or unequal.

[0070] In addition, in the embodiment of the present utility model, the reflective coating 101 can be coated on the greenhouse film slot 100 by dipping, extrusion, electrophoresis, spraying, etc.

[0071] For example, Figures 13 to 15 As shown, the reflective coating 101 is coated on the greenhouse film slot 100 by a dipping process, which specifically includes:

[0072] The greenhouse film slot 100 is pushed forward by the first supporting roller 301 by using the plastic powder dipping unit, and is limited by the vertical roller 302 to push the greenhouse film slot 100 into the electric heating box 300. The edge of the greenhouse film slot 100 is rapidly heated up in the heating box, and enters the plastic powder slot 303 after passing through the first heat insulation ring 304. The high-temperature edge of the greenhouse film slot 100 contacts the plastic powder in the plastic powder slot 303, and the plastic powder is melted and wrapped on the greenhouse film slot 100. Since there is residual plastic powder inside the greenhouse film slot 100 after dipping, an internal plastic powder cleaning mechanism is required. As the greenhouse film slot 100 is rapidly cooled down, the plastic powder dipping of the greenhouse film slot 100 is completed and can be offline.

[0073] For example, Figures 16 to 18 As shown, the reflective coating 101 is coated on the greenhouse film slot 100 by an extrusion processing method, which specifically includes:

[0074] The extruder unit is used to flow the coating material into the extrusion mechanism through the upper hopper 401. The extrusion mechanism includes a motor reducer 402, a second heat insulation ring 403, a heat insulation ring 304, an extrusion screw 404, a filter plate 405 and a heating device 407. The extrusion mechanism squeezes the coating material into the overmolding mold 400. The overmolding mold 400 divides the fluid material into two along the internal channel and enters the first groove edge 110 and the second groove edge 120. The coating material is hot-extruded and wrapped on the first groove edge 110 and the second groove edge 120 to form Reflective coating 101; the greenhouse film slot 100 is held up by the second roller 406, continuously moves from right to left (i.e., the direction of the arrow), and slowly passes through the overmolding mold 400. The extrusion mechanism continuously wraps the coating material on the first groove edge 110 and the second groove edge 120. The greenhouse film slot 100 wrapped with the coating material needs to enter the cooling chamber 408, and usually cold wind at about 15°C is blown to the reflective coating 101 to condense and shape the reflective coating 101, and then the wrapped greenhouse film slot 100 is taken out to complete the coating work.

[0075] The utility model also provides a greenhouse, comprising a greenhouse film 200, a clamping spring 210 and the greenhouse film clamping slot 100 of the above embodiment, wherein the greenhouse film 200 is placed in the greenhouse film clamping slot 100, and the clamping spring 210 clamps the greenhouse film 200 to the inner wall of the clamping slot. The greenhouse can be a greenhouse or a sun room.

[0076] like Figure 8 As shown, after the greenhouse film 200 is installed in the greenhouse, the portion of the greenhouse film 200 that passes through and passes through the greenhouse film slot 100 is in close contact with the first arc segment 112 and the second arc segment 122. At the same time, the greenhouse film 200 can also be parallel to or in close contact with the second straight line segment 113 and the fourth straight line segment 123. On the inner wall of the groove, the clamping spring 210 makes the greenhouse film 200 in close contact with the first arc portion 131 and the second arc portion 141; the clamping spring 210 fastens the greenhouse film 200 in the greenhouse film slot 100.

[0077] The greenhouse film slot 100 provided by the utility model is provided with a reflective coating 101 on at least a part of the contact portion between the greenhouse film slot 100 and the greenhouse film 200, so as to isolate the greenhouse film slot 100 and the greenhouse film 200, and avoid direct contact between the greenhouse film 200 and the greenhouse film slot 100, thereby reducing the wear of the greenhouse film 200 by the greenhouse film slot 100; at the same time, the reflective coating 101 can reflect and isolate heat, reduce the temperature of the greenhouse film slot 100, and increase the service life of the greenhouse film 200.

[0078] Furthermore, in the greenhouse provided by the utility model, since it is provided with the greenhouse film slot 100 as described above, it also has the various advantages as described above.
