Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary technology for extruders, specifically an auxiliary extrusion mechanism for an extruder. Background Technology
[0002] An extruder is a type of machinery widely used in the plastics and rubber processing industry. Its core function is to plasticize, mix, and shape materials using the pressure and shear force generated by the rotation of the screw. During operation, molten material is extruded into the die head in a quantitative, pressure, and temperature manner. The material passes through the die to obtain a certain cross-sectional geometry and size, and then undergoes cooling, shaping, and other processes to obtain the finished product.
[0003] As a core piece of equipment in plastics and rubber processing, extruders can produce plastic pipes of various diameters and applications, such as water supply pipes, drainage pipes, and gas pipes. As a commonly used processing device, it usually requires auxiliary pipe traction equipment during operation. However, because the pipe temperature is not reduced in time during extrusion, traction can easily cause pipe deformation, affecting product quality. Therefore, an auxiliary discharge mechanism for extruders is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary discharge mechanism for extruders, which has advantages such as strong practicality and good cooling effect, and solves the problem that the extruder is prone to deformation when traction due to poor cooling effect during the discharge process.
[0005] To achieve the above-mentioned objectives of high practicality and good cooling effect, this utility model provides the following technical solution: an auxiliary discharge mechanism for an extruder, including a mounting flange, a plurality of outer shell plates disposed on the side of the mounting flange, a material guiding assembly disposed on the outer side of the outer shell plate, and a cooling assembly disposed on the side of the outer shell plate;
[0006] The material guiding assembly includes several connecting rods disposed on the outer side of the outer shell plate, a connecting shaft rotatably connected to the sides of both ends of the connecting rods, and a guide wheel disposed on the side of the connecting shaft;
[0007] The cooling assembly includes several locking tubes disposed on the side of the outer shell plate, a cooling ring tube fixedly installed at the bottom of the locking tube, several water outlet holes opened on the inner wall of the cooling ring tube, a connecting bend threaded to the top of the locking tube, and a water supply pipe fixedly installed on the side of the connecting bend.
[0008] Furthermore, the outer shell plate has an arc-shaped structure, and multiple outer shell plates form a ring structure nested on the side of the mounting flange. The opposite side surface of the outer shell plate is provided with a positioning groove for use with the mounting flange.
[0009] Furthermore, the surface of the outer shell plate is provided with a recessed groove for use with the connecting rod, and the surface of the outer shell plate is provided with a plurality of through grooves for use with the guide wheel.
[0010] Furthermore, the guide wheel has a rotating shaft inside, and the two ends of the connecting shaft are respectively embedded in the side of the rotating shaft of the two guide wheels and fixedly installed with the rotating shaft by plugging.
[0011] Furthermore, a number of locking slots are provided on an adjacent side of the outer shell plate, and the locking tubes penetrate vertically through the locking slots to the outer side of the outer shell plate and are slidably connected to the inner sidewall of the locking slots.
[0012] Furthermore, the cooling ring tube is a hollow annular structure, the cavity of the locking tube is connected to the inner cavity of the cooling ring tube, and the water outlet holes are evenly distributed on the inner wall of the cooling ring tube.
[0013] Furthermore, both the connecting rod and the water supply pipe are arc-shaped structures used in conjunction with the outer shell plate, and the water supply pipe has an inlet on the outer side of the middle section.
[0014] Compared with the prior art, the present invention provides an auxiliary discharge mechanism for an extruder, which has the following beneficial effects:
[0015] 1. The auxiliary discharge mechanism of this extruder uses nuts to fix the mounting flange to the outside of the extruder's discharge port. The water inlet and the external water pump are connected by a pipeline to supply water. The cooling water passes through the water supply pipe to the connecting bend and enters the clamping pipe, and then enters the cooling ring pipe. The water is sprayed through the water outlet on the discharge port of the extruder and sent to the outer wall of the pipe inside the outer shell plate. After carrying away the heat of the pipe, the cooling purpose is achieved.
[0016] 2. The auxiliary discharge mechanism of this extruder continuously discharges material, which enters the interior of the outer shell plate. The guide wheel inside the outer shell plate wraps and supports the outer wall of the material. As the material moves forward, the guide wheel rotates under the friction of the material. At the same time, the cooling ring pipe continuously cools the internal material, improving the cooling efficiency and preventing deformation during subsequent pipe traction. This solves the problem of deformation during traction due to poor cooling effect during extruder discharge. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 4 In this embodiment, an extruder auxiliary discharge mechanism includes a mounting flange 1, several outer shell plates 2 disposed on the side of the mounting flange 1, a material guiding assembly 3 disposed on the outer side of the outer shell plate 2, and a cooling assembly 4 disposed on the side of the outer shell plate 2.
[0024] In this embodiment, the outer shell plate 2 has an arc-shaped structure, and multiple outer shell plates 2 form a ring structure nested on the side of the mounting flange 1. The opposite side surface of the outer shell plate 2 is provided with a positioning groove 21 for use with the mounting flange 1.
[0025] Multiple outer shell plates 2 are assembled into a cylindrical structure and nested on the side of the mounting flange 1. The mounting flange 1 is fixedly installed at the outlet position of the extruder through the mounting holes and nuts, thus wrapping the outlet. The nuts inside the mounting holes firmly fix the side wall of the outer shell plate 2 to the side of the mounting flange 1 through the nuts. At the same time, the positioning groove 21 prevents the outer shell plate 2 from rotating, thus forming a stable installation structure.
[0026] In this embodiment, the surface of the outer shell plate 2 is provided with a recessed slot 22 for use with the connecting rod 31. The connecting rod 31, inside the recessed slot 22, fixes the guide wheel 33 while simultaneously wrapping and defining the side of the outer shell plate 2, forming a ring-shaped fixing structure on the outer side of the outer shell plate 2 to ensure the stability of the overall structure. Additionally, the surface of the outer shell plate 2 is provided with several through slots 23 for use with the guide wheel 33. The guide wheel 33 passes through the through slots 23 to support the pipes passing through the interior of the outer shell plate 2, allowing the pipes to move smoothly.
[0027] In this embodiment, the material guiding assembly 3 includes several connecting rods 31 disposed on the outside of the outer shell plate 2, connecting shafts 32 rotatably connected to the two ends of the connecting rods 31, and guide wheels 33 disposed on the side of the connecting shafts 32.
[0028] In this embodiment, the guide wheel 33 is provided with a rotating shaft inside. The two ends of the connecting shaft 32 are respectively embedded in the rotating shaft sides of the two guide wheels 33 and are fixedly installed with the rotating shaft by plugging. The connecting shaft 32 fixes the connecting rod 31 on both sides of the guide wheel 33 and connects and fixes it with the rotating shaft, so that the guide wheel 33 can rotate smoothly outside the annular structure of the rotating shaft and the connecting shaft 32.
[0029] In this embodiment, the cooling component 4 includes several locking tubes 41 disposed on the side of the outer shell plate 2, a cooling ring tube 42 fixedly installed at the bottom of the locking tube 41, several water outlet holes 43 opened on the inner side wall of the cooling ring tube 42, a connecting bend 44 threadedly connected to the top of the locking tube 41, and a water supply pipe 45 fixedly installed on the side of the connecting bend 44.
[0030] In this embodiment, a plurality of locking slots 24 are provided on an adjacent side of the outer shell plate 2. The locking tube 41 vertically penetrates the locking slot 24 to the outside of the outer shell plate 2 and is slidably connected to the inner side wall of the locking slot 24. The locking tube 41 passes through the locking slot 24 to limit the cooling ring pipe 42 to the inside of the outer shell plate 2 and supplies water to the cooling ring pipe 42.
[0031] It should be noted that the water supply pipe 45 needs to be connected to an external water supply pump to supply water in order to cool the internal moving pipes of the outer shell 2.
[0032] In this embodiment, the cooling ring pipe 42 is a hollow annular structure. The cavity of the locking pipe 41 is connected to the inner cavity of the cooling ring pipe 42. The water outlet holes 43 are evenly distributed on the inner side wall of the cooling ring pipe 42. The water supply pipe 45 and the connecting bend pipe 44 limit the locking pipe 41 on the outside of the outer shell plate 2. The cooling ring pipe 42 fixes the locking pipe 41 on the inside of the outer shell plate 2, thereby ensuring that the cooling component 4 is stably fixed on the inner and outer sides of the outer shell plate 2.
[0033] In this embodiment, the connecting rod 31 and the water supply pipe 45 are both arc-shaped structures used in conjunction with the outer shell plate 2. The water supply pipe 45 has an inlet 451 on the outer side of the middle part. The inlet 451 is connected to an external water supply pump to supply water to the water supply pipe 45, thereby cooling the pipes passing through the inside of the outer shell plate 2.
[0034] The working principle of the above embodiments is as follows:
[0035] By using nuts to fix the mounting flange 1 to the outside of the extruder's discharge port, the water inlet 451 and the external water supply pump are connected by a pipeline to supply water. The cooling water passes through the water supply pipe 45 to the connecting bend 44 and enters the clamping pipe 41, and then enters the cooling ring pipe 42. The water is sprayed through the water outlet 43 onto the discharge port of the extruder and sent to the outer wall of the pipe inside the outer shell plate 2. After carrying away the heat of the pipe, the cooling purpose is achieved.
[0036] In addition, after the material is continuously discharged from the extruder and enters the interior of the outer shell plate 2, the guide wheel 33 inside the outer shell plate 2 wraps and supports the outer wall of the material. As the material moves forward, the guide wheel 33 rotates under the friction of the material. At the same time, it works with the cooling ring pipe 42 to continuously cool the internal material, improve the cooling efficiency, and avoid deformation during subsequent pipe traction. This solves the problem that the material is prone to deformation during traction due to poor cooling effect during the extruder discharge process.

The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
