Description

Technical Field

[0001] The utility model relates to a water pipe extruder. Background Art

[0002] An extruder is a device that extrude materials such as plastics, metals, and foods through a die. It is widely used in the fields of plastic processing, metal processing, and food industry. The working principle of an extruder is to extrude materials into products of desired shapes through heating, melting, and shearing.

[0003] The basic structure of the extruder mainly includes the following parts:

[0004] Feeding system: used to feed raw materials (such as plastic granules) into the extruder, generally including a hopper and a feeding screw.

[0005] Extrusion system: mainly composed of a screw and a barrel. The rotation of the screw moves the material forward and heats and melts it.

[0006] Heating system: includes heater and temperature control system, used to heat the barrel and screw to make the material reach a molten state.

[0007] Die head and mold: installed at the front end of the extruder, extrude the molten material into shape through molds of different shapes.

[0008] Cooling system: used to cool the extruded products to solidify them, generally including cooling water tanks and air cooling devices.

[0009] Control system: used to control various parameters of the extruder, such as temperature, pressure, screw speed, etc., to ensure the stability of the extrusion process and the quality of the product.

[0010] The extruder can output a water pipe of a corresponding shape by setting the shape of the screw outlet to a ring shape, and by weaving metal wires outside the water pipe, the water pipe has the characteristics of high pressure resistance and high strength.

[0011] For existing extruders, materials are generally put into the hopper, melted and transported through the screw to extrude the water pipe. The materials are generally discarded plastic boxes, plastic parts, etc. For these wastes, they generally need to go through a crushing and cutting process to convert them into smaller plastics before being put into the hopper.

[0012] Therefore, it is necessary to add a crushing and cutting machine before putting it into the hopper, which increases the purchase cost and energy consumption. Utility Model Content

DETAILED DESCRIPTION

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply 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 a limitation on the present invention.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0029] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like 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 an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1 As shown, a water pipe extruder includes a frame 1. A housing 2 is provided on the frame 1. A screw 3 is provided in the housing 2, and a discharge port 4 is provided at one end of the screw 3. The discharge port 4 can be set in a ring shape to achieve the purpose of extruding the water pipe. Among them, the other end of the screw 3 passes through the housing 2 and is connected to a drive belt assembly 5, and the drive belt assembly 5 is connected to a motor 6. When the motor 6 works, the drive belt assembly 5 transmits power to the screw 3, and the screw 3 rotates to transport and extrude the incoming plastic. The above is the structure of a general extruder, which is a prior art, so it is not repeated.

[0032] The core technical solution of this application is as follows:

[0033] like Figure 2 , Figure 3As shown, in order to achieve the purpose of cutting the input plastic. The present application is provided with a hopper 7 on one side of the shell 2. The hopper 7 is connected to the shell 2 and is used to input materials. An active roller 8 and a driven roller 9 are provided on the top of the hopper 7. The active roller 8 and the driven roller 9 are connected to the bearings of the hopper 7, and one end passing through the hopper 7 is respectively connected to a gear 10 and a gear 2 11. Correspondingly, a plurality of correspondingly arranged blades 12 are provided on the active roller 8 and the driven roller 9. When the plastic is input between the active roller 8 and the driven roller 9, it is cut into smaller plastics by the blades 12, and then the plastic enters the shell 2 along the hopper 7, and is heated, transported and extruded by the screw 3. The shape and spacing of the above-mentioned blades 12 can be adjusted according to actual needs.

[0034] Correspondingly, gear 10 meshes with gear 2 11, and a transmission belt assembly 13 is connected between the active roller 8 passing through one end of gear 10 and the screw 3. The transmission belt assembly 13 is generally composed of two transmission wheels and a transmission belt. When the screw 3 rotates, the active roller 8 is driven to rotate through the transmission belt assembly 13, thereby driving the driven roller 9 to rotate, so that the plastic entering between the active roller 8 and the driven roller 9 is cut. As mentioned above, when the speed of the screw 3 increases, the rotation rate of the active roller 8 and the driven roller 9 also increases, which has a greater cutting force on the plastic entering therein.

[0035] In addition, one side of gear 10 is meshed with gear 3 14. Gear 3 14 is meshed with gear 4 15. Gear 3 14 and gear 4 15 are respectively connected to the hopper 7 and the frame 1 through the shaft bearing. Gear 4 15 is connected to the conveyor belt assembly 16. The conveyor belt assembly 16 is composed of a conveyor belt and the shafts on both sides of the conveyor belt, which will not be described here. Among them, the conveyor belt is a rubber belt with a certain friction. When the active roller 8 and the driven roller 9 rotate, gear 10 rotates clockwise, so that gear 3 14 rotates counterclockwise and gear 4 15 rotates clockwise. When gear 4 15 rotates clockwise, it drives the conveyor belt to move, and the staff places the corresponding plastic waste on the conveyor belt, and drives the plastic waste to move up into the hopper 7 through friction, so as to achieve the purpose of automatic transportation.

[0036] Correspondingly, a guide frame 17 is also provided between the top of the conveyor belt and the hopper 7. The large plastic waste on the conveyor belt first enters the guide frame 17, and slides into the hopper 7 by its own gravity, realizing automatic feeding.

[0037] As mentioned above, when the screw 3 rotates faster, the speed of conveying plastic is faster, and the speed of cutting plastic also increases accordingly. The rotation speed of the screw 3 can be adjusted according to actual needs, thereby achieving better efficiency of plastic processing and extruding water pipes.

[0038] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
