[0002] Wrapped storage tanks are pressure vessels made by winding plastic materials such as PPH, PP, HDPE, or a mixture of glass fiber and resin, softening them, and then demolding them after cooling. Compared with traditional metal storage tanks, fiberglass storage tanks, etc., wrapped storage tanks have the advantages of light weight and low cost, so wrapped storage tanks have good prospects for use in industrial production.

[0003] In the prior art, the method for making a wound storage tank is as follows: after heating and melting plastic particles, the plastic particles are extruded through an extruder, and the extruded plastic is in a strip shape. The strip-shaped plastic is then tightly wound on the side of a cylindrical mold in a spiral manner, and the mold is removed after the plastic is cooled and formed, so that the body of the wound storage tank is obtained. Finally, a tank bottom and a tank cover are respectively installed at both ends of the tank body to obtain a wound storage tank product.

[0004] In actual use, the wound storage tanks manufactured by the above method have the defect of insufficient strength, and the tank body is at risk of rupture, especially when strong acid and strong alkali solutions are stored in the wound storage tank, serious safety accidents may occur; the production of multi-layer storage tanks requires multiple reciprocating movements of the mold, which is inefficient, and the production is carried out using a single extruder, which is costly. Obviously, the equipment for producing single-layer wound storage tanks can no longer meet the increasingly diverse use requirements of wound storage tanks, and the existing technology needs to be further improved. Summary of the invention

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0026] In this text, relative terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. The orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "top", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention 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 should not be construed as a limitation of the present invention.

[0027] As Figures 1 to 5 shown, a multifunctional plastic tank winding device includes an extrusion mechanism. The extrusion mechanism includes at least two first extrusion mechanisms 1, and the at least two first extrusion mechanisms 1 are respectively arranged on the periphery of the mold to extrude a first material and wind it on the mold 8. The mold 8 is driven by a driving mechanism to move past the first extrusion mechanism 1 so that a single layer or multiple layers of the first material are attached to the surface of the mold 8 to achieve winding.

[0028] By setting at least two first extrusion mechanisms 1, according to the production requirements of plastic storage tanks, one or more first extrusion mechanisms 1 are turned on to extrude the first material. When producing multi-layer storage tanks, after multiple first extrusion mechanisms 1 are sequentially started and the first layer of the first material is attached to the surface of the mold 8, the first material is continuously extruded and wound outside the first material. It is possible to simultaneously extrude multiple first extrusion mechanisms 1 and wind them on the surface of the mold 8, realizing the diversification of the device functions, expanding the scope of use of the device, thereby greatly improving the extrusion and winding efficiency, and increasing the production capacity and benefits.

[0029] In the multifunctional plastic tank winding device of this embodiment, the extrusion mechanism further includes a second extrusion mechanism 2. The second extrusion mechanism 2 is located between at least two first extrusion mechanisms 1, and the second extrusion mechanism 2 is arranged on the periphery of the mold 8 to extrude a second material and wind it on the mold 8.

[0030] Specifically, by setting the second extrusion mechanism 2, after the first extrusion mechanism 1 extrudes the first material and winds it on the surface of the mold 8, the second extrusion mechanism 2 extrudes the second material and winds it outside the first material, and then another first extrusion mechanism 1 continues to extrude the first material and wind it on the surface of the second material, realizing the winding production of a sandwich structure storage tank. By arranging the sandwich layer between the first materials as described above, the strength of the tank body of the storage tank is increased, and the deformation of the storage tank is prevented to meet the use requirements of the storage tank. At the same time, conditions are provided for the production and manufacture of larger plastic storage tanks.

[0031] Preferably, the first extrusion mechanism 1 is a plastic extruder, and the first material extruded by it is softened plastic materials such as strip-shaped PPH and PP. The specific structure of the plastic extruder can refer to the prior art and will not be elaborated here; the second extrusion mechanism 2 is a plastic round tube extruder, and the second material extruded by it is a plastic round tube. In addition, the second material can also be glass fiber or a mixture of glass fiber and resin, or other materials.

[0032] In the multifunctional plastic tank winding equipment of this embodiment, several second extrusion mechanisms 2 are provided, and several second extrusion mechanisms 2 are respectively installed between two adjacent first extrusion mechanisms 1 so that the second material is located between two layers of the first material.

[0033] Specifically, multiple second extrusion mechanisms 2 are respectively located between two adjacent first extrusion mechanisms 1, and the second extrusion mechanism 2 may not be installed between two adjacent first extrusion mechanisms 1. Through the above settings, as Figure 4 and Figure 5 shown, after a layer of the first material is attached to the surface of the mold 8, one or more layers of the first material can be continuously extruded through the first extrusion mechanism 1 for winding, or the second material can be extruded through the second extrusion mechanism 2 and wound on the surface of the first layer of the first material. Thus, various combinations of the first material on both the inner and outer sides and the sandwich layer of the first material and the second material are realized, thereby increasing the functional diversity of the plastic winding equipment and greatly increasing the structural diversity of the plastic storage tank to produce storage tanks with higher strength and more complex structures to meet different usage requirements.

[0034] In the multifunctional plastic tank winding equipment of this embodiment, two groups of first extrusion mechanisms 1 are provided. The two groups of first extrusion mechanisms 1 are arranged oppositely and on the same side of the mold 8, and a second extrusion mechanism 2 is arranged between the two groups of first extrusion mechanisms 1.

[0035] Specifically, in this embodiment, two first extrusion mechanisms 1, that is, plastic extruders, are arranged on the same side of the mold 8 and oppositely, so that the material pretreatment parts of the plastic extruders are far away from each other, making full use of the space.

[0036] When two plastic extruders and the round tube extruder between them are started simultaneously, a plastic storage tank with a round tube sandwich layer is produced to improve the strength of the storage tank; when any one of the first extrusion mechanisms 1 is started, a traditional single-layer storage tank is produced, or the mold 8 is driven to reciprocate to produce a multi-layer storage tank; as Figure 3 shown, when two first extrusion mechanisms 1 are started, a double-layer storage tank is produced, or the mold 8 is driven to reciprocate to produce a storage tank with three or more layers. After two layers are wound, one of the first extrusion mechanisms 1 can be closed during the return stroke of the mold to realize the winding production of a three-layer storage tank. Through the above settings, the production function of the plastic winding equipment is diverse, and the types of storage tanks produced are numerous, thus better meeting the market demand.

[0037] In the multifunctional plastic tank winding equipment of this embodiment, two first extrusion mechanisms 1 are horizontally arranged along the extending direction of the mold 8. The first extrusion mechanism 1 includes an extrusion head 3. The two extrusion heads 3 are arranged at intervals and are respectively perpendicular to the mold 8 to evenly extrude the first material and attach it to the mold 8.

[0038] Specifically, the two first extrusion mechanisms 1 are arranged oppositely so that the parts for preprocessing the material in the extrusion mechanism are far away from each other, thereby realizing the approach of the two extrusion heads 3, making the structure more compact. The second extrusion mechanism 2 is located between the two extrusion heads 3.

[0039] By setting the extrusion head 3 perpendicular to the mold 8, it is convenient for the strip-shaped plastic to be closely attached to the mold 8, realizing tight winding and improving the quality of the wound storage tank. A pressing roller is arranged below the extrusion head 3 to press the strip-shaped plastic onto the mold 8 or press the round tube onto the surface of the strip-shaped plastic, so that the materials are tightly wound around each other.

[0040] In the multifunctional plastic tank winding equipment of this embodiment, a heating mechanism is further included. The heating mechanism is arranged on the periphery of the mold 8 and is located on one side of the extrusion mechanism to heat the mold 8 so that the material extruded by the extrusion mechanism adheres to the mold 8.

[0041] Specifically, the heating mechanism is arranged on the side where the two first extrusion mechanisms 1 are far away from each other. Before the first material extruded by the first extrusion mechanism 1 contacts the mold 8, the surface of the mold 8 is preheated to increase the temperature, so that the strip-shaped plastic can effectively adhere when it contacts the mold 8. At the same time, the adjacent two circles of strip-shaped materials are closely attached to each other, improving the production quality of the storage tank.

[0042] In the multifunctional plastic tank winding equipment of this embodiment, the heating mechanism includes a flame spraying component 4 and a heating plate component 5. The flame spraying component 4 and the heating plate component 5 are respectively arc-shaped and match the surface shape of the mold 8 to realize uniform heating of the surface of the mold 8.

[0043] Specifically, the flame spraying component 4 is set to spray fire on the mold 8 to facilitate the adhesion of the strip-shaped material to the mold 8. The heating plate component 5 is set to heat the surface of the strip-shaped material to facilitate the adhesion between adjacent two circles of strip-shaped materials, or to heat the surface of the strip-shaped plastic to facilitate the adhesion of the round tube to the strip-shaped plastic.

[0044] Preferably, it is set to be arc-shaped to make the surface of the mold 8 heat evenly, thereby ensuring the adhesion effect between the strip-shaped material and the mold.

[0045] In the multifunctional plastic tank winding equipment of this embodiment, a winding platform is further included. The winding platform includes a guide rail 6 and a sliding frame 7 located above the guide rail 6 for carrying the mold 8. The sliding frame 7 is driven by a driving mechanism to drive the mold 8 to move on the guide rail 6 to realize material winding.

[0046] Specifically, the first extrusion mechanism 1 and the second extrusion mechanism 2 are located on the same side of the winding platform. When the mold 8 moves on the winding platform and passes through the first extrusion mechanism 1 or the second extrusion mechanism 2, the extrusion mechanism extrude the material onto the mold 8 to achieve winding. The sliding frame 7 provides support for the mold 8. While the driving mechanism drives the sliding frame 7 to slide along the guide rail 6, the driving mechanism drives the mold 8 to rotate on the sliding frame 7 to achieve plastic winding.

[0047] In the multifunctional plastic can winding equipment of this embodiment, winding roller groups for driving the mold 8 to rotate are respectively arranged at both ends of the sliding frame 7, and the driving mechanism includes a first motor 10 for driving the winding roller group to rotate. The winding roller group includes two groups of winding rollers 11 with adjustable relative distances. The distance between the two groups of winding rollers 11 is adjusted to support molds of different sizes.

[0048] Specifically, two first motors 10 are provided and are arranged along the diagonal of the sliding frame 7. The winding roller 11 is rotatably installed on the adjusting frame through a rotating shaft. The adjusting frame and the sliding frame 7 are slidably connected through a guide rail structure. The rotating shaft is arranged along the extension direction of the guide rail 6. The first motor 10 is fixedly connected to the adjusting frame, so as to follow the movement of the adjusting frame to drive the winding roller 11 to rotate, and drive the mold 8 on the winding roller 11 to rotate through friction force for winding.

[0049] Preferably, the two mounting frames located on the same side are respectively threadedly connected to the two sides of the bidirectional screw rod 9, the bidirectional screw rod 9 is rotatably connected to the sliding frame 7, and one end passes through the sliding frame 7 and is connected to the third motor. The forward and reverse rotation of the third motor drives the bidirectional screw rod 9 to rotate forward and reverse, thereby realizing the adjustment of the distance between the two adjustment frames and the winding roller 11, supporting molds 8 of different sizes and driving the mold 8 to rotate.

[0050] In the multifunctional plastic can winding equipment of this embodiment, the guide rail 6 includes a sliding rail 12 with a tooth groove on the side, and the driving mechanism includes a driving gear meshingly connected to the sliding rail 12. The driving gear is connected to the output end of the second motor 13 through a reducer transmission. The second motor 13 cooperates with the sliding rail 12 through the driving gear to drive the mold 8 to move horizontally along the guide rail 6.

[0051] Specifically, the sliding rail 12 is located in the middle of the guide rail 6, the second motor 13 is fixed on the sliding frame 7, and the driving gear rotates in the horizontal plane, cooperating with the tooth groove on the sliding rail 12 to realize the overall horizontal movement of the sliding frame 7 and realize the winding of the length direction of the storage tank.

[0052] Preferably, the second motor 13 uses a servo motor, which has high precision and is convenient for controlling the movement speed of the carriage 7, enabling the mold 8 to move at a uniform speed in the horizontal direction. As a result, the pitch of the strip material wound on the surface of the mold 8 is consistent, the pattern on the surface of the storage tank is consistent, the connection between the strip materials is tight, and the winding quality of the storage tank is improved.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
