Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, and more specifically, it relates to a lightweight plastic composite sheet metal processing device. Background Technology

[0002] The core of the composite board consists of three layers: the middle layer is the reinforcing layer, which is composed of a mixture of plastic substrate and reinforcing fiber and is the core support for strength and lightweight; the two sides are the substrate layers, which are mainly composed of pure thermoplastic plastic and play the role of wrapping and protecting the reinforcing layer and improving the surface flatness. The three layers are tightly bonded together by a melt composite pressing process to form an integral structure.

[0003] Based on the above, this method requires combining three layers of boards and then processing them, which is slow, inconvenient for rapid shaping, and lacks the function of simultaneously and streamlinedly combining three sets of composite boards. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a lightweight plastic composite sheet processing device, which solves the problems mentioned in the background art that the existing processing device requires combining three layers of sheets before processing, resulting in slow preparation efficiency, inconvenience for rapid shaping, and a lack of function for synchronously and streamlinedly combining three sets of composite sheets.

[0005] The purpose and effect of this utility model's lightweight plastic composite board processing device are achieved by the following specific technical means:

[0006] A lightweight plastic composite sheet processing device includes a conveyor frame. Two sets of conveyor rollers are rotatably arranged at the top center of the conveyor frame, and a conveyor belt is rotatably arranged around the conveyor rollers. A conveyor motor is fixedly arranged on one side of the conveyor frame, and the conveyor motor is connected to one set of conveyor rollers. Three sets of support rollers are rotatably arranged below the top center of the conveyor frame, and three sets of pressing rollers are rotatably arranged above the top center of the conveyor frame. The pressing rollers are perpendicularly aligned with the support rollers. Three sets of support frames are fixedly arranged on one side of the top of the conveyor frame. Each support frame has an extrusion channel fixedly arranged above the side of the support frame closest to the conveyor frame, and a conveyor channel is connected above each extrusion channel. A mixing chamber is fixedly arranged on the top of the support frame, and the bottom of the mixing chamber is connected to the conveyor channel. Three sets of heat dissipation plates are fixedly arranged on the top of the conveyor frame, and five electric fans are arranged in each heat dissipation plate.

[0007] Furthermore, the support rollers and pressing rollers have the same diameter, the three sets of support rollers are at the same horizontal height, and the height of the three sets of pressing rollers gradually increases from front to back.

[0008] Furthermore, the upper part of the extrusion channel is cylindrical, and the bottom of the extrusion channel is a flat outlet; the lower outlet of the conveying channel is connected to the middle of the top of the extrusion channel.

[0009] Furthermore, a spiral propeller is rotatably installed inside the conveying channel, and a feed motor is fixedly installed on one side of the conveying channel, with the feed motor and the spiral propeller being connected in a transmission connection.

[0010] Furthermore, a top seat is fixedly installed on the top of the mixing chamber, a mixing motor is fixedly installed on the top of the top seat, and an agitator is fixedly installed on the shaft end of the mixing motor; a resistance heater is installed in the inner wall of the mixing chamber.

[0011] Furthermore, an opening cover is rotatably provided on one side of the top seat, and the opening cover and the top seat form a disc shape; a solenoid valve is connected to the bottom outlet of the mixing chamber.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This system enables multi-layer synchronous process flow, significantly improving preparation efficiency. Through the design of three independent mixing chambers, conveying channels, and extrusion channels, it can simultaneously complete the melting, precise feeding, and preliminary shaping of raw materials for the bottom layer, intermediate reinforcing layer, and top layer of the composite board. Combined with the vertical alignment and pressing structure of the support roller and pressing roller, it eliminates the cumbersome steps of making individual layers and then combining them, achieving one-time molding process flow and significantly shortening the preparation cycle.

[0014] To ensure the forming accuracy of the sheet and the stability of interlayer adhesion, the speed of the screw propeller in the middle layer conveying channel can be adjusted independently. Combined with the flat outlet design of the extrusion channel, the thickness of each layer can be precisely controlled, especially to meet the thickening requirements of the middle reinforcing layer. The three sets of pressing rollers are set to gradually rise from front to back, and with the horizontal support of the support rollers, a progressive pressing is achieved. This not only avoids the deformation of the sheet in the molten state, but also enhances the adhesion of the three-layer structure and improves the structural stability of the finished product.

[0015] To accelerate the shaping process and ensure the surface quality of the finished product, the heat dissipation plate integrated into the conveyor frame and multiple sets of electric fans form an efficient cooling system, which can quickly cool and shape the pressed sheet material, reducing the risk of deformation caused by natural cooling. At the same time, the integrated heating and stirring design of the mixing chamber ensures that the raw materials melt evenly, and the pressurized conveying of the screw propeller makes the surface of the extruded sheet material smoother, further improving the appearance and performance of the finished product.

[0024] Example 1:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a lightweight plastic composite board processing device, including a conveyor frame 1. Two sets of conveyor rollers 101 are rotatably arranged at the top center of the conveyor frame 1. A conveyor belt 102 is rotatably arranged around the conveyor rollers 101. A conveyor motor 103 is fixedly arranged on one side of the conveyor frame 1, and the conveyor motor 103 is connected to one set of conveyor rollers 101 for transmission. Three sets of support rollers 2 are rotatably arranged below the top center of the conveyor frame 1. Three sets of pressing rollers 3 are rotatably arranged above the top center of the conveyor frame 1. The pressing rollers 3 are perpendicularly aligned with the support rollers 2. Three sets of support frames 4 are fixedly arranged on one side of the top of the conveyor frame 1. Each support frame 4 has an extrusion channel 5 fixedly arranged on the side of the support frame 4 closest to the conveyor frame 1. Each extrusion channel 5 is connected to a conveying channel 6. A mixing chamber 7 is fixedly mounted on the top of the support frame 4. The bottom of the mixing chamber 7 is connected to the conveying channel 6. Three sets of heat dissipation plates 8 are fixedly arranged on the top of the conveyor frame 1. Each heat dissipation plate 8 is equipped with five sets of electric fans.

[0027] Among them, the support roller 2 and the pressing roller 3 have the same diameter, the three sets of support roller 2 have the same horizontal height, and the height of the three sets of pressing roller 3 gradually increases from front to back.

[0028] The upper part of the extrusion channel 5 is cylindrical, and the bottom of the extrusion channel 5 is a flat outlet; the lower outlet of the conveying channel 6 is connected to the middle of the top of the extrusion channel 5.

[0029] The conveying channel 6 is equipped with a rotating screw propeller 601 inside, and a feed motor 602 is fixedly installed on one side of the conveying channel 6. The feed motor 602 is connected to the screw propeller 601 for transmission.

[0030] The mixing chamber 7 is equipped with a top seat 701, a mixing motor 702 is fixedly mounted on the top of the top seat 701, and a stirrer 703 is fixedly mounted on the shaft end of the mixing motor 702; a resistance heater is installed in the inner wall of the mixing chamber 7.

[0031] An opening cover 704 is rotatably mounted on one side of the top seat 701, and the opening cover 704 and the top seat 701 form a disc shape; a solenoid valve is connected to the bottom outlet of the mixing chamber 7.

[0032] Raw material melting and stirring output

[0033] The raw materials are poured into the mixing chamber 7, the materials are melted by the heater, the stirring motor 702 is started to drive the stirrer 703 to rotate, and after the materials are mixed evenly, the solenoid valve below the mixing chamber 7 is opened to output the liquid material.

[0034] Liquid conveying and sheet forming

[0035] The feed motor 602 is started to drive the screw propeller 601 to rotate. The screw propeller 601 is used to transport and pressurize the liquid material to the extrusion channel 5, and the liquid material is extruded from the extrusion channel 5 to form a plate and shape it. Because the intermediate layer is thicker, the speed of the intermediate screw propeller 601 needs to be increased to ensure that the intermediate layer reaches the required thickness.

[0036] Sheet material conveying and cooling / shaping

[0037] The conveyor motor 103 is started to drive the conveyor roller 101 to rotate, which in turn drives the conveyor belt 102 to move the plate. After the plate is initially formed, it is squeezed to the specified thickness by the support roller 2 and the pressing roller 3, and then cooled down quickly by the heat dissipation plate 8 and the electric fan. After cooling down, the plate is shaped.

[0038] Multi-layer synchronous pressing and finished product output

[0039] The middle layer is directly pressed onto the bottom plate by the pressing roller 3, and the upper layer is simultaneously pressed onto the middle layer by the pressing roller 3. After the synchronous pressing is completed, the finished plate is produced and unloaded from the tail end of the conveyor belt 102.

[0040] Example 2:

[0041] Based on Example 1, if a direct melting device is used, it can replace the mixing chamber 7. The melting device can be directly connected to the conveying channel 6, and the molten material can be input into the conveying channel 6 for subsequent preparation.

[0042] The specific usage and function of this embodiment are as follows:

[0043] In this utility model, when in use, the raw materials are poured into the mixing chamber 7, the materials are melted by the heater, the stirring motor 702 is started to drive the stirrer 703 to rotate and stir the materials, and then the solenoid valve below the mixing chamber 7 is opened to output the liquid material.

[0044] The feed motor 602 is started to drive the screw propeller 601 to rotate. The screw propeller 601 is used to transport the liquid material to the extrusion channel 5 and pressurize it to extrude the extrusion channel 5, so as to shape the plate. The middle layer is thicker, so the speed of the middle screw propeller 601 needs to be increased to ensure that it can become thicker.

[0045] The conveyor motor 103 is started to drive the conveyor roller 101 to rotate, and then the conveyor belt 102 rotates to move the plate. After the plate is initially formed, the plate is squeezed to a specified thickness by the support roller 2 and the pressing roller 3. Then the plate passes through the heat dissipation plate 8 and is quickly cooled by the electric fan. After cooling, the plate is shaped.

[0046] Based on the above principle, the middle layer is directly pressed onto the bottom plate by the pressing roller 3, and the upper layer is pressed onto the middle layer by the pressing roller 3. The pressing is carried out simultaneously, and finally a plate is made and unloaded from the tail end of the conveyor belt 102.
