Description

Technical Field

[0001] This utility model belongs to the field of extruder technology, and in particular relates to a tooling that can improve the temperature fluctuation of extrusion heating. Background Technology

[0002] An extruder is a plastic processing machine that uses the pressure and shear force generated by the rotation of a screw to plasticize, mix, and continuously extrude solid materials. Its core function is to provide uniformly molten raw materials for the production of plastic products. It is widely used in the manufacture of pipes, films, profiles, and other products. When the material is fed into the extruder, the first three zones of the extruder are the first to come into contact with the raw material. Due to the size of the feed and the instability of the temperature, it is difficult to control the temperature of the first three zones of the extruder heating zone stably. This results in large temperature fluctuations when the temperature of the extruder heating zone is measured by a temperature probe, causing unstable feed rate and irregular pressure fluctuations, which in turn leads to thickness deviations. A tooling that can reduce temperature fluctuations is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a tooling that can improve extrusion heating temperature fluctuations, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tooling for improving extrusion heating temperature fluctuations, comprising a copper block, the copper block being a cylinder with a length of 15mm and a diameter of 5.8mm, the copper block being vertically disposed on the bottom side of the extruder heating zone, the upper end of the copper block being fixedly connected to the inside of the extruder heating zone, the upper end of the copper block not contacting the material in the extruder heating zone, the lower end of the copper block being located at the axis of the heat insulation cylinder, the lower end of the copper block abutting against the temperature probe, and the upper end of the heat insulation cylinder being threadedly connected to the bottom side of the extruder heating zone by multiple bolts thereon, the upper surface of the heat insulation cylinder being in close contact with the extruder heating zone.

[0005] Beneficial effects This invention provides a tooling that can improve extrusion heating temperature fluctuations, and has the following advantages compared with the prior art: 1. Since the upper end of the copper block is located inside the extruder heating zone, and copper has good thermal conductivity, the temperature of the extruder heating zone can act on the copper block, thus raising the overall temperature of the copper block. Furthermore, because the temperature probe is close to the lower end of the copper block, it can monitor the temperature of the copper block in real time. This allows for monitoring of the temperature of the extruder heating zone through the copper block as a carrier. The copper block increases the distance between the temperature probe and the extruder heating zone, effectively preventing rapid changes in material temperature from affecting the accuracy of temperature measurement. This effectively filters out the influence of instantaneous material temperature, resulting in more precise monitoring of the extruder heating zone temperature. Additionally, because the copper block is inside the insulation cylinder, the cylinder effectively isolates it, preventing excessively high or low external temperatures from affecting its temperature.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0013] Please see Figures 1-4This invention provides a tooling for improving extrusion heating temperature fluctuations, comprising a copper block 202. The copper block 202 is a cylinder with a length of 15 mm and a diameter of 5.8 mm. The copper block 202 is vertically disposed on the bottom side of the extruder heating zone 101, and its upper end is fixedly connected to the inside of the extruder heating zone 101. The upper end of the copper block 202 does not contact the material inside the extruder heating zone 101, and its lower end is insulated. At the axis of the cylinder 201, the lower end of the copper block 202 is pressed against the temperature probe 204, and the upper end of the heat insulation cylinder 201 is threadedly connected to the bottom side of the extruder heating zone 101 by a plurality of bolts 203 provided thereon, and the upper surface of the heat insulation cylinder 201 is in close contact with the extruder heating zone 101; the copper block 202 should be installed in the area of ​​the extruder heating zone 101 near its center line to avoid accidental contact by the user, and heat sources should be avoided around it to avoid interfering with the temperature of the copper block 202.

[0014] In the above embodiment, since the upper end of the copper block 202 is located inside the extruder heating zone 101 and the copper block 202 has good thermal conductivity, the temperature of the extruder heating zone 101 can act on the copper block 202, thereby raising the overall temperature of the copper block 202. Furthermore, since the temperature probe 204 is closely attached to the lower end of the copper block 202, the temperature probe 204 can monitor the temperature of the copper block 202 in real time. Thus, the temperature of the extruder heating zone 101 is monitored using the copper block 202 as a carrier. Under the action of the copper block 202, the distance between the temperature probe 204 and the extruder heating zone 101 increases, effectively preventing rapid changes in material temperature from affecting the accuracy of temperature measurement in the heating zone 101. This effectively filters out the influence of instantaneous material temperature, resulting in more accurate monitoring of the temperature of the extruder heating zone 101. Moreover, since the copper block 202 is located inside the heat insulation cylinder 201, the heat insulation cylinder 201 effectively isolates the copper block 202, preventing excessively high or low external temperatures from affecting its temperature.

[0015] Specifically, the temperature probe 204 is fixedly connected to the connecting wire 205, and the lower end of the heat insulation cylinder 201 is provided with a through groove 206, through which the connecting wire 205 passes; the connecting wire 205 is used to connect to the power supply that powers the temperature probe 204, and to the display screen that displays the temperature measured by the temperature probe 204.

[0016] Specifically, the extruder heating zone 101 is provided with a connecting assembly for stable contact between the temperature probe 204 and the lower end of the copper block 202. The connecting assembly includes a frame 207, the temperature probe 204 is fixedly connected to the upper surface of the frame 207, and the frame 207 is vertically slidably disposed on the inner wall of the heat insulation cylinder 201.

[0017] Specifically, a guide rod 208 is vertically fixedly connected to the lower end face of the frame 207, and the lower end of the guide rod 208 slides through the through hole at the bottom of the heat insulation cylinder 201. A pull plate 301 is fixedly connected to the lower end of the guide rod 208, and the outer diameter of the guide rod 208 is smaller than the inner diameter of the through hole at the bottom of the heat insulation cylinder 201.

[0018] Specifically, a spring 209 is sleeved on the guide rod 208, and the upper and lower ends of the spring 209 are respectively fixedly connected to the lower surface of the frame 207 and the inner bottom surface of the heat insulation cylinder 201.

[0019] In the above embodiment, the user can pull down the pull plate 301, causing the frame 207, which is fixedly connected to it, to begin linear sliding within the heat insulation cylinder 201. At this time, the distance between the temperature probe 204 and the copper block 202 gradually increases, and the guide rod 208 is further compressed to increase its elastic potential energy, thereby stopping the temperature probe 204 from continuing to measure the temperature of the copper block 202. When it is necessary to continue measuring, the user should stop pulling the pull plate 301, causing the spring 209 to begin to rebound. At this time, the spring 209 begins to push the frame 207, which is fixedly connected to it, causing the frame 207 to push the temperature probe 204, which is fixedly mounted on it, to slide towards the copper block 202 until the temperature probe 204 is pushed against the lower end face of the copper block 202, thereby preventing the temperature probe 204 from separating from the copper block 202 and thus preventing the temperature of the copper block 202 from being effectively measured.

[0020] Specifically, the frame 207 is provided with a cooling component to prevent the temperature inside the heat insulation cylinder 201 from becoming too high. The cooling component includes a temperature sensor 302, which is fixedly connected to the frame 207 away from the copper block 202. The side wall of the heat insulation cylinder 201 is provided with an arc-shaped groove 303, which is located on the side of the temperature sensor 302. The temperature sensor 302 is connected to a power supply for powering it and a display screen for displaying the measured temperature.

[0021] In the above embodiment, since the copper block 202 has good thermal conductivity, the temperature inside the heat insulation cylinder 201 will gradually rise, thereby affecting the accuracy of the temperature measured by the temperature probe 204. At this time, the user can monitor the temperature inside the heat insulation cylinder 201 in real time through the temperature sensor 302, so that the user can control the temperature inside the heat insulation cylinder 201 to be slightly lower than the temperature range of the extruder heating zone 101.

[0022] Specifically, the length and width of the arc-shaped groove 303 are both smaller than the length and width of the arc-shaped cover plate 304, and the arc-shaped cover plate 304 is rotatably disposed on the outer wall of the heat insulation cylinder 201, and the arc-shaped cover plate 304 is tightly attached to the outer wall of the heat insulation cylinder 201.

[0023] Specifically, the arc-shaped cover plate 304 is threaded with a screw 305, and the lower end face of the screw 305 abuts against the outer wall of the heat insulation cylinder 201.

[0024] In the above embodiment, the user can loosen the screw 305 to stop limiting the arc-shaped cover plate 304. At this time, the user can rotate the arc-shaped cover plate 304 to stop blocking the arc-shaped groove 303. Then the heat insulation cylinder 201 is no longer in a closed state. By opening the arc-shaped groove 303, the temperature inside the heat insulation cylinder 201 is reduced more quickly.

[0025] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0026] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0027] (1) Detachable connection: Components are fixed together using screws, splines, wedges, etc. This type of connection allows for disassembly during maintenance without damaging the parts. However, the specifications of the connectors used must be correct. (Such as the length of bolts, keys, and wedges), and tighten them properly.

[0028] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, during connection, [the following should be noted]: Pay attention to process quality, technical testing, and remedial measures (such as correction, polishing, etc.).

[0029] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0030] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
