Description

Technical Field

[0001] This invention relates to the field of nylon pigment materials technology, and in particular to an environmentally friendly weather-resistant nylon pigment material and its processing method and apparatus. Background Technology

[0002] In the current technology, the processing of environmentally friendly weather-resistant nylon pigment materials requires the use of a twin-screw extruder. The twin-screw extruder was developed based on the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, venting performance, and extrusion stability, it is now widely used in the molding and processing of extruded products. The basic mechanism of the extrusion process can be simply described as a screw rotating in the barrel and pushing the plastic forward. The screw structure is a sloping surface or ramp wound around the central layer, the purpose of which is to increase the pressure in order to overcome greater resistance.

[0003] A search revealed that prior art CN202220675814.5 discloses a pelletizing structure for a twin-screw extruder, comprising a mounting platform, a splash guard, and a pelletizing head. An extrusion mechanism and a drive mechanism are mounted on the mounting platform. A screw is rotatably connected to the inner side of the extrusion mechanism, and a pelletizing head is mounted at one end of the extrusion mechanism. This invention reduces equipment costs by using a screw to drive the pelletizing head; and it rapidly cools the interior of the splash guard by utilizing a motor-driven fan blade rotation combined with the inclusion of heat dissipation holes.

[0004] Although the aforementioned patent does not require a separate power source for the pelletizing head, it additionally sets up two motors to drive two fan blades to rotate for heat dissipation and cooling. This approach increases the overall cost of the equipment and fails to truly achieve the advantage of reducing equipment cost investment. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly weather-resistant nylon pigment material and its processing method and apparatus, which can reduce equipment cost investment.

[0006] To achieve the above objectives, the present invention provides an environmentally friendly weather-resistant nylon pigment material processing device, including a twin-screw extruder body, wherein an extrusion screw extends outward from one side of the twin-screw extruder body, and also includes auxiliary components; The auxiliary components include a protective cover, an extruder head, a splined shaft, a ventilation plate, a mounting bracket, blades, a bearing housing, a cutting tool component, a limiting component, and a protective component. The protective cover is mounted on the twin-screw extruder body. The extruder head is mounted on the twin-screw extruder body and located outside the extruder screw. The splined shaft is inserted into the extruder screw and limited by the bearing housing and the limiting component, and passes through the ventilation plate. The ventilation plate is installed inside the protective cover. The mounting bracket is installed on the side of the splined shaft away from the extruder head. Multiple blades are integrally formed with the mounting bracket and are evenly spaced in a ring. The bearing housing is mounted on the protective cover. The cutting tool component is fixed on the extruder screw and located inside the extruder head. The limiting component is located on both sides of the bearing housing. The protective component is located on the side of the protective cover near the bearing housing.

[0007] The cutting tool component includes a retaining ring and blades. The blades are uniformly spaced in an integral ring on the retaining ring and are detachably connected to the extrusion screw.

[0008] The limiting component includes a T-shaped spacer and a mating component. The T-shaped spacer is sleeved and installed on the splined shaft and abuts against the mounting bracket. The mating component is located on the bearing seat near the splined shaft.

[0009] The mating components include a threaded ring and a pressure cap, wherein the threaded ring is threadedly connected to the spline shaft; and the pressure cap is detachably connected to the bearing housing.

[0010] The protective component includes a fixing frame and a connecting component. The fixing frame is installed on the end face of the protective cover away from the extrusion screw. The connecting component is disposed inside the fixing frame.

[0011] The connecting component includes a rectangular plate and a ventilation mesh, wherein the rectangular plate is welded inside the fixed frame and the ventilation mesh is installed on the rectangular plate.

[0012] The environmentally friendly weather-resistant nylon pigment material processing device also includes an isolation component, which includes a sliding sleeve and a disc. The sliding sleeve is slidably connected to the optical axis end of the spline shaft and is fixed by the disc, which is integrally set.

[0013] One type of environmentally friendly weather-resistant nylon pigment material can be pelletized during processing using the aforementioned environmentally friendly weather-resistant nylon pigment material processing device.

[0014] One method for processing environmentally friendly weather-resistant nylon pigment material involves pelletizing using the aforementioned environmentally friendly weather-resistant nylon pigment material processing device, and includes the following steps: After mixing the raw materials according to the required weight and proportions, add them to the feed hopper of the twin-screw extruder body; Plasticize the material, then feed the color powder into the twin-screw extruder body from both sides, and output it after traction and cooling; The material is pelletized using an environmentally friendly, weather-resistant nylon color powder processing device located on the discharge side of the twin-screw extruder. After drying, an environmentally friendly weather-resistant nylon pigment material is obtained.

[0015] This invention discloses an environmentally friendly weather-resistant nylon pigment material processing device. The extrusion head of the twin-screw extruder body can discharge material. At this time, after the extrusion screw extends to the outside of the extrusion head, it can directly drive the cutting tool component to perform extrusion material pelletizing processing when rotating. At the same time, the rotation of the extrusion screw will drive the spline shaft to rotate, and the rotation of the spline shaft will drive the mounting frame to rotate, which can drive multiple blades to rotate to form a fan structure for heat dissipation. No additional drive device is required, thereby achieving the effect of reducing equipment cost investment. Attached Figure Description

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1:

[0025] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of an environmentally friendly, weather-resistant nylon pigment material processing device. Figure 2 This is a schematic diagram of the splined shaft. The present invention provides an environmentally friendly weather-resistant nylon pigment material processing device, comprising a twin-screw extruder body 101, an extrusion screw 102, and auxiliary components. The auxiliary components include a protective cover 103, an extrusion head 104, a splined shaft 105, a ventilation plate 106, a mounting frame 107, blades 108, a bearing seat 109, a cutting tool component, a limiting component, and a protective component. The cutting tool component includes a retaining ring 110 and a blade 111. The limiting component includes a T-shaped spacer 112 and a mating component. The mating component includes a threaded coil 113 and a pressure cap 114. The protective component includes a fixing frame 115 and a connecting component. The connecting component includes a rectangular plate 116 and a ventilation mesh 117. The aforementioned solution can achieve the effect of reducing equipment cost investment. It is understood that the aforementioned solution can reduce equipment cost investment.

[0026] In this embodiment, an extrusion screw 102 extends outward from one side of the twin-screw extruder body 101, while the other extrusion screw does not extend to the outside. Furthermore, all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the art. Moreover, this application is mainly used to protect mechanical devices, so this application will not explain the control method and circuit connection in detail.

[0027] The protective cover 103 is mounted on the twin-screw extruder body 101. The extrusion head 104 is mounted on the twin-screw extruder body 101 and located outside the extrusion screw 102. The spline shaft 105 is inserted into the extrusion screw 102 and is limited by the bearing seat 109 and the limiting member, and passes through the ventilation plate 106. The ventilation plate 106 is installed inside the protective cover 103. The mounting bracket 107 is installed on the side of the spline shaft 105 away from the extrusion head 104. A plurality of blades 108 are integrally formed with the mounting bracket 107 and are arranged in a ring with uniform spacing. The bearing seat 109 is mounted on the protective cover 103. The cutting tool component is fixed on the extrusion screw 102 and located inside the extrusion head 104. The limiting member is located on both sides of the bearing seat 109. The protective member is located on the side of the protective cover 103 near the bearing seat 109. The protective cover 103 has a rectangular lug on the front and an L-shaped lug on the rear for easy bolt fixing. The extrusion screw 102 has a splined cavity at its end for easy insertion and installation of the splined end of the splined shaft 105. The end of the splined shaft 105 furthest from the splined end is fitted with a rotating bearing for positioning. The splined shaft 105 has multiple evenly spaced rectangular grooves, each with an axially spaced circular hole. These holes facilitate the insertion and positioning of the circular rod on the locking block of the mounting bracket 107. The mounting bracket 107 is fully positioned after installation via the T-shaped spacer 112. The ventilation plate 106 has multiple L-shaped connectors at its top for easy bolt fixing and multiple ventilation holes with a diameter smaller than the product particle diameter. The bearing seat 109 is fixed with locating pins and bolts.

[0028] Secondly, the blades 111 are integrally and evenly spaced in a ring on the fixing ring 110, and are detachably connected to the extrusion screw 102. After the fixing ring 110 is fitted onto the extrusion screw 102, it is fixed to the stepped platform of the extrusion screw 102 by multiple bolts.

[0029] Then, the T-shaped spacer 112 is fitted onto the splined shaft 105 and abuts against the mounting bracket 107; the mating component is located on the side of the bearing housing 109 near the splined shaft 105. The T-shaped spacer 112 abuts against the inner ring of one side of the rotating bearing mounted on the splined shaft 105 and simultaneously limits the mounting bracket 107; the mating component fully limits the rotational bearing.

[0030] Furthermore, the threaded ring 113 is threadedly connected to the splined shaft 105; the pressure cap 114 is detachably connected to the bearing housing 109. The threaded ring 113 and the spacer cooperate to abut against the inner ring of the rotating bearing mounted on the splined shaft 105 on the other side. The pressure cap 114 is fixed by bolts and has a T-shaped structure with a clearance through hole in the center, used to abut against the outer ring of the rotating bearing. The outer ring of the rotating bearing on the other side is limited by the limiting structure of the bearing housing 109.

[0031] Furthermore, the fixing frame 115 is installed on the end face of the protective cover 103 away from the extrusion screw 102; the connecting component is disposed inside the fixing frame 115. The fixing frame 115 is fixed by bolts. The connecting component is used for ventilation and safety protection.

[0032] Finally, the rectangular plate 116 is welded inside the fixed frame 115; the ventilation mesh 117 is installed on the rectangular plate 116. The ventilation mesh 117 is fixed by welding or by bolts.

[0033] When using this invention to reduce equipment cost investment, the extrusion head 104 of the twin-screw extruder body 101 can discharge material. Since the extrusion screw 102 extends to the outside of the extrusion head 104, it can directly drive the cutting tool component to perform extrusion pelletizing when rotating. At the same time, the rotation of the extrusion screw 102 will drive the spline shaft 105 to rotate together. After the spline shaft 105 rotates, it drives the mounting frame 107 to rotate, which can drive multiple blades 108 to rotate to form a fan structure for heat dissipation. In this application, when the extrusion screw 102 rotates, it directly drives the fan structure formed by the mounting frame 107 and the blades 108 to rotate, without the need for an additional drive device, thereby achieving the effect of reducing equipment cost investment.

[0034] Example 2:

[0035] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the sliding sleeve. Based on the first embodiment, the present invention provides an environmentally friendly weather-resistant nylon pigment material processing device. The environmentally friendly weather-resistant nylon pigment material processing device also includes an isolation component, which includes a sliding sleeve 201 and a disc 202.

[0036] The sliding sleeve 201 is slidably connected to the optical axis end of the spline shaft 105 and fixed by the integrally formed disc 202. The sliding sleeve 201 and the disc 202 form a T-shaped structure when integrally formed. The disc 202 is fixed by bolts.

[0037] In this embodiment, by providing the sliding sleeve 201, the ventilation plate 106 and the spline shaft 105 can be isolated from each other during transmission, which helps to extend the service life of the ventilation plate 106. At the same time, the sliding sleeve 201 can also provide stable rotational support for the spline shaft 105.

[0038] Example 3:

[0039] like Figure 4 As shown, where Figure 4 This is a schematic diagram of the overall structure of an environmentally friendly weather-resistant nylon pigment material processing device. Based on the first embodiment, the present invention provides an environmentally friendly weather-resistant nylon pigment material processing device, which further includes a deodorization component, comprising a U-shaped tube 301, a guide tube 302, and a connecting tube 303.

[0040] The U-shaped tube 301 is welded to the bottom of the protective cover 103, and the guide tube 302 and the connecting tube 303 are welded thereon. The outlet of the connecting tube 303 is connected to the input pipe of the exhaust fan, and an activated carbon filter is installed on the outlet side of the exhaust fan. Multiple guide tubes 302 are welded to the bottom of the U-shaped tube 301 for communication, and the connecting tube 303 is connected to the U-shaped tube 301 after welding.

[0041] In this embodiment, during processing, the exhaust fan is turned on to generate suction. If the falling particles have an odor, the odor will disperse and enter the U-shaped tube 301 through the guide tube 302. Finally, the gas is drawn into the activated carbon filter and discharged through the connecting tube 303 in conjunction with the exhaust fan, thus performing gas filtration treatment.

[0042] An environmentally friendly weather-resistant nylon pigment material can be pelletized during processing using the aforementioned environmentally friendly weather-resistant nylon pigment material processing device.

[0043] like Figure 5 As shown, where Figure 5 This is a flowchart of a processing method for an environmentally friendly weather-resistant nylon pigment material according to the present invention.

S4: After drying, an environmentally friendly weather-resistant nylon pigment material is obtained.

[0044] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
