Description

Technical Field

[0001] This utility model relates to the field of polycarbonate sheet processing technology, and in particular to a multi-cavity extrusion molding equipment for polycarbonate striped sheets. Background Technology

[0002] Polycarbonate sheets are widely used in industrial production due to their excellent physical properties. The conventional production method is to extrude molten polycarbonate material through a die using extrusion molding equipment, and then cool and compact it through cooling rollers to finally shape it into a sheet.

[0003] However, existing extrusion molding equipment typically uses single-cavity molds, extruding only one sheet at a time. This results in low overall production efficiency, making it difficult to meet the growing market demand for large-volume sheet production. Furthermore, when producing polycarbonate sheets with striped surfaces, traditional equipment, due to the smooth surface of its cooling rollers, can only produce flat sheets and cannot directly form stripes. Typically, stripes are formed after extrusion molding through subsequent processes such as secondary hot pressing or engraving. This not only increases production steps and complicates the process but also extends the production cycle and increases manufacturing costs, preventing the achievement of integrated, efficient production.

[0004] Therefore, this utility model proposes a multi-cavity extrusion molding equipment for polycarbonate striped sheets to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-cavity extrusion molding equipment for polycarbonate striped sheets, aiming to improve the problems of low production efficiency and inability to integrally form surface stripes during the extrusion process in the existing extrusion molding equipment for polycarbonate striped sheets, which leads to a complex process flow.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-cavity extrusion molding apparatus for polycarbonate striped sheets includes: an apparatus body, a mold, a conveyor belt, multiple cooling rollers, and a fine-tuning component.

[0010] Preferably, the fine-tuning component includes a hydraulic pump, a hydraulic rod driven by the hydraulic pump, and a connecting plate. The output end of the hydraulic rod is fixedly connected to the connecting plate, and a plurality of cooling rollers are rotatably mounted on the connecting plate via a connecting block.

[0011] Preferably, the device further includes a circulation component that is in communication with the interior of all the cooling rollers for circulating refrigerant into the interior of the cooling rollers.

[0012] Preferably, the circulation assembly includes a cold liquid tank and a delivery pipe, and the interior of the cooling roller is provided with a refrigeration pipe. The refrigerant in the cold liquid tank passes through the delivery pipe and is distributed by the distribution pipe before finally entering the refrigeration pipe.

[0013] Preferably, the output end of the mold is provided with a lip, and the polycarbonate melt extruded from the multi-cavity structure is output to the conveyor belt through the lip.

[0014] Preferably, the stripe forming structure consists of a plurality of annular grooves evenly distributed along the axial direction of the cooling roller.

[0015] Preferably, the device further includes a mounting plate and a retaining shell.

The mold is accommodated inside the retaining shell, and the retaining shell is fixedly connected to the mounting plate.

[0016] Preferably, the discharge end of the equipment body is connected to an extension box, and the end of the conveyor belt extends into the interior of the extension box.

[0017] This utility model has the following beneficial effects:

The technical effect of simultaneously extruding multiple sheets and integrally completing the surface stripe shaping is achieved, which greatly improves production efficiency and simplifies the process.

[0019] 2. In this utility model, by setting a fine-tuning component to uniformly adjust the lifting of all cooling rollers with striped molding structures, and cooperating with the circulation component to continuously and stably cool the rollers, the problem of difficulty in ensuring the accuracy of thickness control and the uniformity of cooling during the compaction and shaping of the sheet material is solved. This achieves precise fine-tuning of the final thickness of the polycarbonate striped sheet and ensures uniform cooling of the sheet material during the molding process, thereby effectively improving the dimensional accuracy and quality stability of the final product.

[0020] 3. In this utility model, by organically combining the multi-cavity extrusion die, the striped cooling roller, the hydraulic fine-tuning component, and the circulating cooling component, the problems of the traditional equipment being structurally dispersed, having a single function, and being difficult to achieve efficient automated production are solved.

Detailed Implementation

[0028] 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.

[0029] Example:

[0030] Please refer to Figures 1 to 5 This utility model provides a multi-cavity extrusion molding equipment for polycarbonate striped sheets, which aims to solve the problems of low production efficiency, inability to integrally mold striped sheets, and poor coordination of thickness control and cooling uniformity in the existing polycarbonate sheet extrusion equipment.

[0031] like Figures 1-3 As shown, a multi-cavity extrusion molding device for polycarbonate striped sheets includes a device body 1, a mounting plate 6 fixedly connected to the feed end of the device body 1, a mounting groove 7 for fixing the device to a high-temperature heating device on the outer side of the mounting plate 6, a clamping shell 8 fixedly connected to the mounting plate 6, a mold 5 housed inside the clamping shell 8, a conveyor belt 4 disposed inside the device body 1, the conveying path of the conveyor belt 4 being located below the mold 5, and the end of the conveyor belt 4 extending into the interior of an extension box 2, the extension box 2 being connected to the discharge end of the device body 1, multiple cooling rollers 12 disposed above the conveyor belt 4, a fine-tuning component 9 disposed on the top of the device body 1, the fine-tuning component 9 and all cooling rollers 12 forming a lifting adjustment connection for synchronously adjusting the distance between the cooling rollers 12 and the conveyor belt 4, and a circulation component 3 disposed on one side of the device body 1, the circulation component 3 communicating with the interior of all cooling rollers 12 for circulating and conveying refrigerant into the interior of the cooling rollers 12.

[0032] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the mold 5 is designed as a multi-cavity structure, and the surface of the cooling roller 12 is provided with a stripe forming structure that matches the stripes on the surface of the stripe plate.

[0033] Please refer to the following carefully. Figures 1-3 The core structure is described in detail below: Mold 5 has a multi-cavity structure, which is used to divert the polycarbonate molten material entering from the chuck 8 and simultaneously extrude multiple strips of molten material. The output end of mold 5 is equipped with a lip 13. The polycarbonate molten material extruded from the multi-cavity structure is evenly output to the conveyor belt 4 below through the lip 13. This design significantly improves production efficiency. Meanwhile, please refer to... Figure 3 and Figure 4The surface of the cooling roller 12 is provided with a stripe forming structure that matches the stripes on the surface of the striped plate. In a specific embodiment, the stripe forming structure is a plurality of annular grooves evenly distributed along the axial direction of the cooling roller 12. When the high-temperature strip of polycarbonate melt is conveyed to the cooling roller 12 below the conveyor belt 4, the cooling roller 12 with the stripe forming structure presses the melt downward under the action of the fine adjustment component 9. During the cooling and shaping process of the melt, the annular groove structure on its surface is integrally imprinted on the surface of the plate to form the corresponding stripes, realizing the integrated processing of extrusion and stripe shaping.

[0034] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0035] In a preferred embodiment, in order to achieve precise control of the extrusion height of the cooling rollers 12, the fine-tuning component 9 includes a hydraulic pump 901, a hydraulic rod 902, and a connecting plate 10. The hydraulic pump 901 drives the hydraulic rod 902, and the output end of the hydraulic rod 902 is fixedly connected to the connecting plate 10. Multiple cooling rollers 12 are rotatably mounted on the connecting plate 10 via a connecting block 11. By starting the hydraulic pump 901, the hydraulic rod 902 can be driven to move the connecting plate 10 in an overall lifting motion, thereby synchronously adjusting the height of all cooling rollers 12.

[0036] As another preferred embodiment, in order to ensure that the cooling rollers 12 cool continuously, efficiently and uniformly, the equipment also includes a circulation component 3. The circulation component 3 is connected to the interior of all the cooling rollers 12. The circulation component 3 includes a cold liquid tank 301 and a liquid delivery pipe 302. Each cooling roller 12 is provided with a refrigeration pipe 304 inside. The refrigerant in the cold liquid tank 301 flows into the refrigeration pipe 304 inside the corresponding cooling roller 12 through the liquid delivery pipe 302 and the distribution pipe 303, thereby achieving continuous cooling of the roller body.

[0037] In the specific installation structure, in order to facilitate the docking of the equipment with the upstream high-temperature heating equipment and the stable installation of the mold, the equipment also includes an installation plate 6 and a clamping shell 8. The outer side of the installation plate 6 is provided with an installation groove 7 for fixing the equipment to the high-temperature heating equipment. The mold 5 is accommodated inside the clamping shell 8, and the clamping shell 8 is fixedly connected to the installation plate 6. This structure ensures the stability and sealing of the feeding channel.

[0038] In order to collect and guide the formed sheets, an extension box 2 is connected to the discharge end of the equipment body 1, and the end of the conveyor belt 4 extends into the interior of the extension box 2, so as to collect or guide the finally formed polycarbonate striped sheets to the next process.

[0039] Working principle: First, the equipment is fixedly installed to the output end of the high-temperature heating equipment through the mounting groove 7 on the outside of the mounting plate 6. At this time, the polycarbonate material heated at high temperature enters the cassette 8 through the mounting plate 6 and flows into the mold 5. The multi-cavity structure of the mold 5 distributes the molten material into multiple strips, which are then extruded through the lip 13 at the output end of the mold 5 onto the conveyor belt 4 inside the equipment body 1. Then, under the conveyor belt 4, the high-temperature strip of molten material gradually moves to the bottom of multiple cooling rollers 12. At this time, the hydraulic pump 901 at the top of the fine-tuning component 9 is activated. Under the action of the hydraulic pump 901, the hydraulic rod 902 begins to drive the bottom connecting plate 10 downward, thereby causing the cooling rollers 12 inside the connecting block 11 to descend as a whole, thus cooling the molten material. During compaction, the stripe forming structure on the surface of the cooling roller 12 integrally forms the preset stripes on the surface of the polycarbonate sheet. At the same time, the circulation component 3 is also working continuously. The refrigerant inside the cold liquid tank 301 flows steadily into the cooling pipe 304 inside each cooling roller 12 through the inlet pipe 302 and the diversion pipe 303, continuously and efficiently cooling the roller body, thereby ensuring the uniform cooling and shaping of the polycarbonate striped sheet. Finally, the formed sheet is conveyed to the extension box 2 through the conveyor belt 4. By combining multi-cavity extrusion with striped roller cooling and compaction, this utility model solves the problems of low production efficiency, inability to integrally form stripes, and poor coordination between thickness and cooling effect in the prior art.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
