DETAILED DESCRIPTION

[0045] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0047] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] Reference Figure 1, which is the first embodiment of the present invention, proposes a rubber tube, including a tubular body 1, the side wall of the tubular body 1 is wavy, and has a plurality of outer protrusions 101 and inner protrusions 102, and the plurality of outer protrusions 101 and the plurality of inner protrusions 102 are alternately connected; one end of a guide plate 2 is arranged on the inner protrusion 102 and is located in the tubular body 1, and the other end of the guide plate 2 faces one end of the tubular body 1, and the surface of the guide plate 2 and the surface of the inner protrusion 102 are smoothly transitioned.

[0050] In this embodiment, in order to solve the problem that the rubber tube on the sowing equipment in the related art is prone to material clogging and has a low service life, the tubular body 1 is first set to a wave shape, and the specific shape is that it has a plurality of outer convex parts 101 and inner convex parts 102 arranged in sequence. Through the arrangement of the outer convex part 101 and the inner convex part 102, the tubular body 1 has elasticity, enhances flexibility during use, can be suitable for a variety of different connection lengths, and is easy to adjust. In order to avoid the transported materials such as fertilizers and seeds being stuck in the inner convex part 102 of the tubular body 1 when transporting materials, a guide plate 2 is arranged on the inner convex part 102. The guide plate 2 is annular and tilted toward the end of the tubular body 1 where the material is discharged. Therefore, in the process of transporting materials, it can guide the materials, which can not only improve the transportation efficiency of the materials, but also block the materials to prevent the materials from entering the inner convex part 102 during the transportation process. At the same time, when conveying materials, the materials mainly contact the guide plate 2. Therefore, during the use of the rubber tube, the guide plate 2 is the main wear part, which can greatly reduce the risk of the tubular body 1 being worn, thereby reducing the risk of the material leaking from the conveying part of the tubular body 1 during the conveying process. The provision of the guide plate 2 can not only avoid the problem of rubber tube blockage, but also reduce the wear of the tubular body 1, reduce the risk of material leakage, and increase the service life of the rubber tube.

[0051] Furthermore, the cross section of the guide plate 2 is triangular, and the upper surfaces of the plurality of guide plates 2 are parallel to each other.

[0052] In this embodiment, the cross section of the guide plate 2 is triangular, so that the surface of the guide plate 2 itself forms a certain inclination. In accordance with the installation direction of the guide plate 2, the guide plate 2 has a larger inclination angle after installation, and the guiding effect is better. A plurality of guide plates 2 are distributed parallel to each other, so that the force on the material during the conveying process is as much as possible in a uniform direction, and the conveying efficiency is higher. At the same time, accelerating the conveying efficiency of the material can reduce the time for the material to pass through the tubular body 1, thereby further reducing the risk of material blockage.

[0053] Reference Figure 2~Figure 7, which is the second embodiment of the present invention, a rubber tube processing equipment is proposed, including an injection molding machine body 3; an inner mold column 4 is arranged on the injection molding machine body 3; there are multiple first molding parts 5, and the multiple first molding parts 5 are arranged on the inner mold column 4 at intervals, the first molding part 5 has an inner cavity, the side wall 501 of the inner cavity and the outer wall 502 of the first molding part 5 are both conical, one end of the outer wall 502 abuts against the adjacent side wall 501, and a first molding cavity 503 is formed between the outer wall 502 and the side wall 501, and the first molding cavity 503 is used to mold the guide plate 2; the outer wall 502 has a large end and a small end, and the second molding part 6 is arranged at the large end; the outer mold 7 is arranged on the injection molding machine body 3, the outer mold 7 covers the first molding part 5 and the second molding part 6, and a second molding cavity 601 is formed between the outer mold 7 and the second molding part 6, and the second molding cavity 601 is used to mold the tubular body 1.

[0054] In this embodiment, due to the existence of the guide plate 2, the rubber tube is not convenient to demould during the injection molding process, so the injection mold is set to a split form. A plurality of first molding parts 5 are set on the inner mold column 4, and the inner wall and outer wall 502 of the first molding part 5 are both conical. After the plurality of first molding parts 5 are abutted in sequence, a first molding cavity 503 for molding the guide plate 2 can be formed between the adjacent inner wall and outer wall 502. Since the plurality of guide plates 2 are parallel to each other, the plurality of first molding cavities 503 are also parallel to each other, so that the demoulding process of the rubber tube is smoother. And the cross section of the guide plate 2 is a triangle, so as the demoulding proceeds, the gap between the one-way plate and the first molding cavity 503 will become larger and larger, further improving the demoulding efficiency. Through the cooperation of the second molding part 6 and the outer mold 7, the molding of the tubular body 1 is completed. When performing the demolding operation, first separate the outer mold 7 and the second molding part 6. After the tubular body 1 is exposed, separate the rubber tube and the second molding part 6 along the length direction of the inner mold column 4, and the guide plate 2 is removed from the first molding cavity 503. During the demolding process, since the rubber tube has a certain ductility, the second molding part 6 will not affect the demolding of the rubber tube.

[0055] Furthermore, the second molding part 6 is annular, and the outer mold 7 includes a mold body 701. The mold body 701 has two, and the two mold bodies 701 are hollow cylinders when buckled together. The inner mold column 4, the first molding part 5 and the second molding part 6 are located in the two mold bodies 701; there are multiple third molding parts 8, and the multiple third molding parts 8 are arranged at intervals on the inner wall of the mold body 701, and the third molding parts 8 are distributed at intervals from the second molding parts 6.

[0056] In this embodiment, for the convenience of demolding, the mold body 701 has two. During the molding process, the two mold bodies 701 are buckled together. During demolding, the two mold bodies 701 are separated. During the separation process, the mold body 701 only needs to be moved along the radial direction of the inner mold column 4. The third molding part 8 is located on the inner wall of the mold body 701. After the mold body 701 is buckled, the third molding part 8 and the second molding part 6 are spaced apart, thereby forming a wavy second molding cavity 601 for molding the outer convex part 101 and the inner convex part 102. When the mold body 701 moves away from the inner mold column 4 in the radial direction, the third molding part 8 will naturally separate from the tubular body 1, which is convenient for demolding.

[0057] Furthermore, the cross-sections of the second molded portion 6 and the third molded portion 8 are both triangular.

[0058] In this embodiment, the cross-sections of the second molded portion 6 and the third molded portion 8 are both set to be triangular, so that the peak positions of the formed outer convex portion 101 and the inner convex portion 102 have a larger thickness, and the strength is higher during the expansion and contraction of the rubber tube, thereby extending the service life of the rubber tube.

[0059] Furthermore, the mold body 701 includes a first connecting portion 7011 and a second connecting portion 7012; there are multiple arc-shaped portions 7013, and the multiple arc-shaped portions 7013 are connected end to end in sequence. The third molding portion 8 is arranged at the connection between two adjacent arc-shaped portions 7013, and the first connecting portion 7011 and the second connecting portion 7012 are respectively arranged on the two arc-shaped portions 7013 located at both ends.

[0060] In this embodiment, the mold body 701 is composed of a first connecting part 7011, a second connecting part 7012 and a plurality of arc-shaped parts 7013. The arc-shaped parts 7013 are arranged to make the edge transition between the tubular body 1 and the outer protrusion 101 smoother, so that during use, the rubber tube can better withstand the force when stretched.

[0061] Furthermore, it also includes a support plate 9, which has two support plates 9. The two support plates 9 are slidably set on the injection molding machine body 3, and the ends of the two support plates 9 close to each other have installation grooves 901, and there are multiple installation grooves 901, which are distributed in parallel and spaced apart, and the outer mold 7 is set in the installation grooves 901; the guide column 10 is set on the injection molding machine body 3, and the support plate 9 is slidably connected to the guide column 10.

[0062] In this embodiment, in order to improve the production efficiency of the rubber tube, a support plate 9 is provided on the injection molding machine body 3, and the mold body 701 is installed in the installation groove 901. A plurality of mold bodies 701 can be installed on the support plate 9 at the same time, so as to complete the injection molding of a plurality of rubber tubes at the same time. During the movement of the support plate 9, the guide column 10 plays a guiding role to prevent the support plate 9 from deviating during the sliding process, thereby affecting the demoulding efficiency and molding effect of the rubber tube.

[0063] Furthermore, the inner mold column 4 has a first air hole 401 and multiple second air holes 402. The first air hole 401 is concentric with the inner mold column 4. The first air hole 401 penetrates from one end of the inner mold column 4 to the other end of the inner mold column 4. A cooling cavity 504 is formed between two adjacent first molding parts 5. The second air hole 402 connects the cooling cavity 504 and the first air hole 401.

[0064] In this embodiment, in order to improve the molding efficiency, the first air hole 401 and the second air hole 402 are provided on the inner mold column 4, wherein after the plurality of first molding parts 5 are installed on the inner mold column 4, in addition to forming the first molding cavity 503 between two adjacent first molding parts 5, a cooling cavity 504 is formed between the end of the first molding part 5 and the inner cavity of another adjacent first molding part 5. The second air hole 402 connects the cooling cavity 504 with the first air hole 401, and after injection molding, cooling gas is introduced into the first air hole 401, and the cooling gas enters the cooling cavity 504 through the second air hole 402, thereby accelerating the cooling molding of the rubber tube and making the cooling molding efficiency of the rubber tube higher.

[0065] Furthermore, multiple first molding parts 5 are slidably arranged on the inner mold column 4, and also include a first connecting member 11, which is arranged at one end of the inner mold column 4 and abuts against the outer wall 502 of the first molding part 5 located at one end; the second connecting member 12 is arranged at the other end of the inner mold column 4, and abuts against the first molding part 5 located at the other end.

[0066] In this embodiment, in order to facilitate the installation of the first molding part 5, a first connecting member 11 and a second connecting member 12 are respectively provided at both ends of the inner mold column 4, and the first connecting member 11 and the second connecting member 12 can be connected to the inner mold column 4 by threading. When installing the first molding part 5, firstly install the first connecting member 11 at one end of the inner mold column 4, then install multiple first molding parts 5 on the inner mold column 4 in sequence, and finally install the second connecting member 12 at the other end of the inner mold column 4.

[0067] Further, the second connecting member 12 includes a limit seat 1201, which is arranged on the inner mold column 4; one end of the limit rod 1202 is slidably arranged on the limit seat 1201, and the other end is abutted against the first molding part 5; the two ends of the first elastic member 1203 are respectively arranged on the limit seat 1201 and the limit rod 1202, for providing a force for the limit rod 1202 to slide close to the first molding part 5.

[0068] In this embodiment, in order to facilitate the separation of the guide plate 2 and the first molding cavity 503, the second connecting member 12 is set in a split form. After the first molding part 5 is installed on the inner mold column 4, the limiting rod 1202 is first sleeved on the inner mold column 4, and then the first elastic member 1203 is sleeved on the inner mold column 4. Finally, the limiting seat 1201 is installed on the inner mold column 4, so that one end of the limiting rod 1202 abuts against the first molding part 5, so that multiple first molding parts 5 are fixed between the first connecting member 11 and the second connecting member 12. Then, the rubber tube can be injection molded. After the injection molding is completed, the rubber tube is quickly cooled by passing gas into the first air hole 401. When the demolding process is performed, the first air hole 401 is blocked and gas is continued to be passed into the first air hole 401. At this time, the introduced gas cannot overflow from the other end of the first air hole 401, and can only enter the cooling cavity 504 from the second air hole 402. After the pressure in the cooling cavity 504 increases, the introduced gas will push the first molding part 5 to slide slightly, and the first elastic member 1203 is compressed, thereby generating gaps between multiple adjacent first molding parts 5, and the gas enters between the guide plate 2 and the first molding part 5, thereby accelerating the demolding efficiency of the rubber tube.
