Description

Technical Field

[0001] This application relates to the field of plastic processing technology, specifically to a plastic strip extrusion device. Background Technology

[0002] A plastic extruder is a molding and processing machine used to extrude heated and softened materials into shapes such as strips, blocks, and sheets.

[0003] A plastic extruder mainly consists of an extrusion barrel, a screw (or plunger), and auxiliary components (metering device and feed port). Its working principle involves multiple steps, including heating, melting, extruding, and molding of the plastic material. Feeding and preheating: The plastic raw material is added to the barrel through a funnel-shaped feeding device and preheated to improve its fluidity and melting effect. The raw material is continuously propelled forward by the rotating screw, while a heater outside the barrel heats it, melting it into a viscous flow state. The combined effect of the screw rotation and barrel heating creates a molten layer within the barrel. The molten plastic reaches the die head (mold) and is extruded into the desired shape according to the product's requirements. The structure and design of the die head have a significant impact on the molding effect. The product is pulled out of the die head and cut to ensure its specifications and quality.

[0004] During the conveying process of plastic granules, the plastic granules in the storage bin are transported to the interior of the heating tank through pipes. When the valve inside the pipe is opened, the heat inside the heating tank will return to the interior of the storage bin through the pipes. Because the temperature is too high, after the temperature is consumed through the pipes, it will still slightly melt the surface of the plastic granules in the storage bin. This will cause the plastic granules in the storage bin to solidify and condense, resulting in the subsequent conveying of plastic granules not being smooth enough. Utility Model Content

[0005] The purpose of this application is to provide a plastic strip extrusion device to solve the problem mentioned in the background art, which causes the plastic particles in the storage bin to agglomerate after solidification, resulting in insufficient smooth conveying of subsequent plastic particles.

[0007] By adopting the above technical solution, the plastic particles can be moved, avoiding direct contact with high temperatures.

[0008] Preferably, the feeding mechanism also has a heat dissipation mesh welded to the inner wall of the through hole of the conveying pipe.

[0012] Preferably, the feeding mechanism further includes a counterweight block integrally formed on one end of the baffle, and the counterweight block is plate-shaped.

[0013] By adopting the above technical solution, the angle of the structure connected on one side can be changed due to weight.

[0014] Preferably, the plastic strip extrusion device further includes a conveying mechanism, which further comprises a drive motor fixed to the outer wall of the heating tank.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0028] Example 1

[0029] Please see Figures 1-4 This embodiment provides a technical solution: a plastic strip extrusion device, including: a heating tank 1, a conveying mechanism 2, a feeding mechanism 3, and a storage box 4;

[0030] The inner wall of the heating tank 1 is equipped with a heating device for melting plastic. The heating tank 1 can melt the plastic granules inside, so that they can be extruded into a specified shape. The outer wall of the heating tank 1 is provided with holes for plastic extrusion, which can provide discharge of the melted plastic granules. The top of the heating tank 1 is provided with a feeding pipe, which can transport the plastic granules into the interior of the heating tank 1.

[0031] The plastic strip extrusion device also includes a conveying mechanism 2, which can provide conveying and movement of plastic particles inside the heating tank 1. The conveying mechanism 2 also has a drive motor 201 fixed on the outer wall of the heating tank 1. The drive motor 201 is connected to the outer wall of the heating tank 1 by bolts and can provide stable rotation of the output end. A screw 202 connected to the output end of the drive motor 201 can drive the plastic particles inside the heating tank 1 to be conveyed during rotation.

[0032] The feeding mechanism 3 is located above the feeding pipe of the heating tank 1. The feeding mechanism 3 can prevent direct contact with the high temperature inside the heating tank 1 during the conveying of plastic granules. The feeding mechanism 3 includes a conveying pipe 301 bolted to the feeding pipe of the heating tank 1. The conveying pipe 301 can convey plastic granules into the interior of the heating tank 1 for subsequent melting. The conveying pipe 301 has through holes on both sides to allow air to enter, thereby reducing the temperature inside the conveying pipe 301. One end of the conveying pipe 301 has a rectangular hole to allow the structure inside the rectangular hole to move stably in the horizontal direction. A cylinder 303 bolted to the outer wall of the conveying pipe 301 can drive the structure connected to the output end to move stably in the horizontal direction inside the conveying pipe 301.

[0033] A push plate 304, bolted to the output end of cylinder 303, can move horizontally to move the plastic granules in conveying pipe 301 to a designated position. A baffle 306, positioned above the push plate 304, prevents plastic granules from falling onto the push plate 304 by fitting against its upper surface during movement. The push plate 304 is horizontally slidably connected within the rectangular hole of conveying pipe 301, providing stability during movement. A storage box 4, bolted to the top of conveying pipe 301, stores the plastic granules.

[0034] The cylinder 303 drives the pusher plate 304 to move, so that the pusher plate 304 no longer blocks the conveying pipe 301, thereby providing the storage box 4 to convey the plastic particles into the inside of the conveying pipe 301. The cylinder 303 is started to drive the pusher plate 304 to move. During the movement of the pusher plate 304, the plastic particles are pushed into the inside of the heating tank 1. At this time, the baffle 306 will be attached to the upper surface of the pusher plate 304 to prevent the plastic particles from falling above the pusher plate 304. When the plastic particles are inside the heating tank 1, they are melted by the heating tank 1. The drive motor 201 drives the screw 202 on the output end to rotate, thereby moving the plastic particles and extruding them from the hole at the other end of the heating tank 1.

[0035] Example 2

[0036] Please see Figures 1-4 This embodiment provides a technical solution: a plastic strip extrusion device, including: a heat dissipation mesh 302, a connecting shaft 305, and a counterweight 307;

[0037] A heat dissipation mesh 302 is welded to the inner wall of the through hole of the conveying pipe 301. The heat dissipation mesh 302 can prevent plastic particles inside the conveying pipe 301 from falling out when the through hole of the conveying pipe 301 is cooled by incoming air. A connecting shaft 305 is welded to the inner wall of the conveying pipe 301. The connecting shaft 305 can change the angle of the structure on the shaft during rotation. The baffle 306 is rotatably connected to the connecting shaft 305. The baffle 306 changes the angle through the connecting shaft 305, so as to fit against the push plate 304. A counterweight 307 is integrally formed on one end of the baffle 306. The counterweight 307 can drive the baffle 306 to change the angle, so that the baffle 306 fits against the push plate 304. The counterweight 307 is plate-shaped and can provide plastic particles to be conveyed into the interior of the conveying pipe 301.

[0038] When the plastic granules move inside the conveying pipe 301, the high temperature of the heating tank 1 being conveyed into the conveying pipe 301 can be cooled by air through the holes opened in the conveying pipe 301. The heat dissipation net 302 can prevent the plastic granules from falling off. The baffle 306 is connected to the counterweight 307, and the angle can be changed through the connecting shaft 305. At this time, the baffle 306 will be attached to the push plate 304, but it will not be too attached to the push plate 304 and the movement will not be unsmooth.

[0039] The operating principle of the plastic strip extrusion device of this application is as follows:

[0040] First, the cylinder 303 drives the push plate 304 to move, so that the push plate 304 no longer blocks the conveying pipe 301, thereby providing the storage box 4 to convey the plastic particles into the conveying pipe 301. The cylinder 303 is started to drive the push plate 304 to move. During the movement of the push plate 304, the plastic particles are pushed into the heating tank 1. When the plastic particles move inside the conveying pipe 301, the high temperature of the plastic particles conveyed into the heating tank 1 can be cooled by air through the holes opened in the conveying pipe 301. The heat dissipation net 302 can prevent the plastic particles from falling off.

[0041] Secondly, at this time, the baffle 306 will adhere to the upper surface of the push plate 304 to prevent plastic particles from falling onto the push plate 304. The baffle 306 is connected to the counterweight 307, thereby changing the angle through the connecting shaft 305. At this time, the baffle 306 will adhere to the push plate 304, and will not adhere too much to the push plate 304, making its movement unsmooth.

[0042] Finally, when the plastic granules are inside the heating tank 1, they are melted by the heating tank 1. The drive motor 201 drives the screw 202 on the output end to rotate, thereby moving the plastic granules and extruding them from the hole at the other end of the heating tank 1.

[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
