Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a PVC insulation material extrusion mechanism. Background Technology

[0002] PVC insulation material is a special insulation material for wires and cables, made from polyvinyl chloride (PVC) resin as the matrix and modified with plasticizers, stabilizers, flame retardants, fillers, and other auxiliary materials. Its core characteristics are that it maintains excellent insulation performance while also offering advantages such as low cost and easy processing, making it widely used in the low-voltage wire and cable field.

[0003] In existing technologies, raw materials are typically extruded into strips of insulating material using an extrusion mechanism. These strips are then cut into granules by a cutting mechanism. Therefore, a complete PVC insulating material granulator includes an extrusion mechanism and a cutting mechanism. The extrusion mechanism extrudes the material into strips, and the cutting mechanism within the extrusion mechanism cuts the strips into granules. However, in existing PVC insulating material extrusion mechanisms, jamming and uneven extrusion can occur, severely affecting the quality and efficiency of the extruded product. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PVC insulation material extrusion mechanism.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a PVC insulation material extrusion mechanism, comprising:

[0006] The drive mechanism includes a drive motor, a first pulley, a second pulley, a transmission belt, and a reducer. The first pulley is mounted on the drive motor to drive the first pulley to rotate. The second pulley is mounted on the reducer. The transmission belt connects the first pulley and the second pulley, thereby enabling the drive motor to drive the second pulley to rotate.

[0007] An extrusion rod includes a rotating rod, a helical blade, and a guide cone. The helical blade is disposed on the rotating rod, and one end of the rotating rod is connected to the reducer to rotate the rotating rod. The guide cone is disposed at the other end of the rotating rod.

[0008] The device includes a feed hopper, a transfer box, and an outer sleeve. The feed hopper is connected to the transfer box, and at least a portion of the extrusion rod passes through the transfer box. The outer sleeve is fitted onto the extrusion rod, and the extrusion rod is rotatable within the transfer box and the outer sleeve.

[0009] Preferably, it also includes a heater, which is disposed on the outer sleeve and wraps around the outer sleeve.

[0010] Preferably, the assembly further includes a granulation component located near the extrusion rod. The granulation component includes a first ferrule having a first through hole extending through the ferrule along its axial direction. At least a portion of the guide cone of the extrusion rod extends into the first through hole of the first ferrule of the granulation component, and the tapered structure of the guide cone extends into the first through hole of the first ferrule.

[0011] Preferably, the granulation assembly further includes an extrusion orifice plate, which is installed together with the first component ring. The extrusion orifice plate includes a first base and an extrusion orifice plate body. The extrusion orifice plate body is installed on the first base and has a preset number of extrusion orifices. The extrusion orifice holes penetrate the extrusion orifice plate body. When the extrusion orifice plate is installed on the first component ring, the first through hole of the first component ring communicates with the extrusion orifice holes of the extrusion orifice plate body.

[0012] Preferably, the granulation assembly further includes an intermediate connecting sleeve, which has a first mounting groove and a second through hole. The first mounting groove is formed by recessing a predetermined depth from one end face of the intermediate connecting sleeve, and the second through hole extends through the intermediate connecting sleeve along its axial direction. The first mounting groove communicates with the second through hole. The first seat of the extrusion plate is inserted into the first mounting groove of the intermediate connecting sleeve, thereby installing the extrusion plate and the intermediate connecting sleeve together. The extrusion hole on the extrusion plate body of the extrusion plate communicates with the second through hole of the intermediate connecting sleeve.

[0013] Preferably, the granulation assembly further includes a granulation body and a flow divider cone. The granulation body is provided with a second mounting groove, which is formed by recessing the outer surface of one end face of the granulation body along the axial direction of the granulation body. The flow divider cone is installed in the second mounting groove, thereby installing the flow divider cone together with the granulation body. At least a portion of the flow divider cone extends into the second through hole of the intermediate connecting sleeve, and there is a gap between the flow divider cone and the intermediate connecting sleeve.

[0014] Preferably, the granulation body is provided with a preset number of granulation through holes. The granulation through holes extend from the outer surface of one end face of the granulation body along a direction parallel to the axial direction of the granulation body. When the flow divider cone is installed on the granulation body, the granulation through holes are distributed around the flow divider cone. When the granulation body is installed to the intermediate connecting sleeve, the granulation through holes communicate with the second through hole of the intermediate connecting sleeve.

[0015] The beneficial effects of this application are as follows: The PVC insulation material extrusion mechanism provided by this application has the advantages of simple structure and convenient assembly. Since a guide cone is provided on the extrusion rod, when the extrusion rod rotates and drives the raw material to move forward to the guide cone, the guide cone guides the raw material to the granulation component, thereby making the flow of the raw material smoother. Since the granulation component includes a diverting cone, and the diverting cone extends into the second through hole of the intermediate connecting sleeve, when the raw material flows into the second through hole of the intermediate connecting sleeve, the raw material becomes thinner and more uniform after being diverted by the diverting cone, which also makes the flow of the raw material smoother. The raw material diverted by the diverting cone also makes granulation easier. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0026] Please refer to Figure 1-7 This application provides a PVC insulation material extrusion mechanism (hereinafter referred to as "the extrusion mechanism"), which includes:

[0027] The drive mechanism includes a drive motor 1, a first pulley 3, a second pulley 4, a transmission belt 5, and a reducer 2. The first pulley 3 is mounted on the drive motor 1 to drive the first pulley 3 to rotate; the second pulley 4 is mounted on the reducer 2, and the transmission belt 5 connects the first pulley 3 and the second pulley 4, thereby enabling the drive motor 1 to drive the second pulley 4 to rotate.

[0028] The extrusion rod 11 includes a rotating rod 111, a spiral blade 112, and a guide cone 113. The spiral blade 112 is disposed on the rotating rod 111. One end of the rotating rod 111 is connected to the reducer 2, thereby causing the rotating rod 111 to rotate. The guide cone 113 is disposed at the other end of the rotating rod 111.

[0029] The system includes a feed funnel 8, a transfer box 7, and an outer sleeve 6. The feed funnel 8 is connected to the transfer box 7, and at least a portion of the extrusion rod 11 passes through the transfer box 7. The outer sleeve 6 is fitted onto the extrusion rod 11, and the extrusion rod 11 can rotate within the transfer box 7 and the outer sleeve 6. Thus, raw material enters the transfer box 7 from the feed funnel 8. When the extrusion rod 11 rotates, under the combined action of the outer sleeve 6 and the extrusion rod 11, the raw material moves along the length of the extrusion rod 11 until it reaches the guide cone 113. After being guided by the guide cone 113, the raw material smoothly flows into the next process. In this application, the rotating rod 111 is connected to the reducer 2 via a coupling. It should be clear to those skilled in the art that the reducer is a known technology, and its main purpose is to convert the high speed of the drive motor 1 to a low speed. Therefore, as long as the speed reduction purpose can be achieved, this application does not limit the structure or brand of the reducer 2. Preferably, the reducer in this application is a single-stage horizontal cycloidal pinwheel reducer.

[0030] Please refer to some embodiments of this application. Figure 1-7 The extrusion mechanism also includes a heater 9, which is disposed on the outer sleeve 6 and encloses the outer sleeve 6. In this application, the heater 9 is energized. It must be understood that the outer sleeve 6 does not participate in rotation; it is the extrusion rod 11 that rotates. Preferably, the heater 9 is a cast aluminum heater.

[0031] Please refer to some embodiments of this application. Figure 1-7 The extrusion mechanism further includes a granulation assembly 10, which is located near the extrusion rod 11. The granulation assembly 10 includes a first component ring 101 having a first through hole 1010 extending axially through the first component ring 101. At least a portion of the guide cone 113 of the extrusion rod 11 extends into the first through hole 1010 of the first component ring 101 of the granulation assembly 10, and the tapered structure of the guide cone 113 extends into the first through hole 1010 of the first component ring 101. Thus, the raw material driven by the rotation of the extrusion rod 11 is guided through the guide cone 113 into the first through hole 1010 of the first component ring 101.

[0032] Please refer to some embodiments of this application. Figure 1-7The granulation assembly 10 further includes an extrusion orifice plate 102, which is installed together with the first component ring 101. The extrusion orifice plate 102 includes a first base 1021 and an extrusion orifice plate body 1022. The extrusion orifice plate body 1022 is installed on the first base 1021. The extrusion orifice plate body 1022 is provided with a preset number of extrusion holes 10220. The extrusion holes 10220 penetrate the extrusion orifice plate body 1022. When the extrusion orifice plate 102 is installed on the first component ring 101, the first through hole 1010 of the first component ring 101 communicates with the extrusion holes 10220 of the extrusion orifice plate body 1022 of the extrusion orifice plate 102. In this way, the raw material flows into the first through hole 1010 of the first component ring 101 and flows through the extrusion hole 10220 on the extrusion plate body 1022. Under the rotation of the extrusion rod 11, the raw material flows into the first through hole 1010 of the first component ring 101 until it flows into and flows through the extrusion hole 10220 on the extrusion plate body 1022.

[0033] Please refer to some embodiments of this application. Figure 1-7 The granulation assembly 10 further includes an intermediate connecting sleeve 103, which is provided with a first mounting groove 1031 and a second through hole 1032. The first mounting groove 1031 is formed by recessing a predetermined depth from one end face of the intermediate connecting sleeve 103. The second through hole 1032 extends through the intermediate connecting sleeve 103 along its axial direction, and the first mounting groove 1031 communicates with the second through hole 1032. The first seat 1021 of the extrusion plate 102 is inserted into the first mounting groove 1031 of the intermediate connecting sleeve 103, thereby enabling the extrusion plate 102 and the intermediate connecting sleeve 103 to be installed together, and the extrusion hole 10220 on the extrusion plate body 1022 of the extrusion plate 102 communicates with the second through hole 1032 of the intermediate connecting sleeve 103. In this way, the raw material flows into the second through hole 1032 of the intermediate connecting sleeve 103 after passing through the extrusion hole 10220.

[0034] Please refer to some embodiments of this application. Figure 1-7The granulation assembly 10 further includes a granulation body 104 and a flow divider cone 105. The granulation body 104 has a second mounting groove 1041, which is formed by a recess along the axial direction of the outer surface of one end face of the granulation body 104. The flow divider cone 105 is installed in the second mounting groove 1041, thereby mounting the flow divider cone 105 together with the granulation body 104. At least a portion of the flow divider cone 105 extends into the second through hole 1032 of the intermediate connecting sleeve 103, and a gap exists between the flow divider cone 105 and the intermediate connecting sleeve 103. Thus, when the raw material flows out from the second through hole 1032, it is diverted by the flow divider cone 105, causing the raw material to flow out through the gap between the flow divider cone 105 and the intermediate connecting sleeve 103. The flow divider cone makes the raw material flowing into the granulation body 104 more uniform and thinner, which is more conducive to granulation and makes the flow of the raw material smoother.

[0035] Please refer to some embodiments of this application. Figure 1-7 The granulation body 104 is provided with a predetermined number of granulation through holes 1042. Each granulation through hole 1042 extends from the outer surface of one end face of the granulation body 104 along a direction parallel to the axial direction of the granulation body 104. When the flow divider cone 105 is installed on the granulation body 104, the granulation through holes 1042 are distributed around the flow divider cone 105. When the granulation body 104 is installed to the intermediate connecting sleeve 103, the granulation through holes 1042 communicate with the second through hole 1032 of the intermediate connecting sleeve 103. Thus, the raw material in the second through hole 1032 of the intermediate connecting sleeve 103 flows out from the granulation through holes 1042 of the granulation body 104 after being diverted by the flow divider cone 105.

[0036] The PVC insulation material extrusion mechanism provided in this application has the advantages of simple structure and convenient assembly. Since a guide cone is provided on the extrusion rod, when the extrusion rod rotates and drives the raw material to move forward to the guide cone, the guide cone guides the raw material to the granulation component, thereby making the flow of the raw material smoother. Since the granulation component includes a diverting cone, and the diverting cone extends into the second through hole of the intermediate connecting sleeve, when the raw material flows into the second through hole of the intermediate connecting sleeve, the raw material becomes thinner and more uniform after being diverted by the diverting cone, which also makes the flow of the raw material smoother. The raw material diverted by the diverting cone also makes granulation easier.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
