Description

Technical Field

[0001] The present invention relates to the technical field of extrusion molding equipment for PP coil raw materials, and specifically to an extrusion molding equipment for the production of PP coil raw materials with rapid cooling. Background Art

[0002] The extrusion molding equipment for the production of PP coil raw materials is an intelligent manufacturing equipment. The traditional extrusion molding equipment for the production of PP coil raw materials has limitations in cooling. It often cools the extruded raw materials through water cooling and air cooling with fixed power. The temperature of the raw materials after being extruded from the extrusion head is not always constant, and the traditional cooling structure cannot be adjusted adaptively. When the raw material temperature is high, the cooling structure with fixed power and fixed cooling distance has a slow cooling speed, low efficiency and high energy consumption for the raw materials, and cannot meet the requirement of rapid cooling, and even causes defects in the products; when the raw material temperature is low, the traditional cooling structure will overcool the raw materials, resulting in waste of resources and affecting the overall production efficiency and product quality. Therefore, we need an extrusion molding equipment for the production of PP coil raw materials with rapid cooling to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide an extrusion molding equipment for the production of PP coil raw materials with rapid cooling to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] The extrusion molding equipment includes a workbench, an extrusion pipe, a driving module, a defoaming module, an extrusion head and a cooling module. The extrusion pipe is arranged on the workbench and fixedly connected to the workbench. The driving module is inserted from one end of the extrusion pipe and fixedly connected to the extrusion pipe. One end of the extrusion head is fixedly connected to the other end of the extrusion pipe, and the other end is fixedly connected to the cooling module. The extrusion head is arranged on the workbench and fixedly connected to the workbench. The defoaming module is arranged at one end of the extrusion pipe close to the extrusion head and rotatably connected to the extrusion pipe. The defoaming module is fixedly connected to the driving module. The cooling module is arranged on the workbench and fixedly connected to the workbench.

[0006] The workbench serves as the installation foundation of the extrusion molding equipment to keep the extrusion molding equipment stable. The molten raw materials enter the extrusion pipe from the inlet of the extrusion pipe. The driving module conveys the raw materials from the inlet of the extrusion pipe to the defoaming module. When the driving module works, it drives the defoaming module to rotate at the same time. When the raw materials pass through the defoaming module, the internal bubbles are eliminated, and then they are extruded through the extrusion head. The extruded strip-shaped raw materials enter the cooling module for rapid cooling, improving the production efficiency.

[0007] Furthermore, a feeding funnel is arranged at the inlet of the extrusion pipe, and the feeding funnel is fixedly connected to the extrusion pipe.

[0008] A feeding funnel is provided to facilitate the continuous entry of a large amount of raw materials into the extrusion tube.

[0009] Furthermore, the driving module includes a driving motor, a screw rod, and a mounting shell. The driving motor is fixedly connected to the workbench, the output rod of the driving motor is fixedly connected to the screw rod. The screw rod passes through the mounting shell, inserts into the extrusion tube, and is rotatably connected to the mounting shell. The screw rod is fixedly connected to the defoaming module. The mounting shell is fixedly connected to the extrusion tube and is arranged at one end of the extrusion tube.

[0010] The mounting shell assists in the fixed positioning of the screw rod. The driving motor drives the screw rod to rotate, and conveys the raw materials in the extrusion tube. Under the continuous conveyance and extrusion of the screw rod, the raw materials are extruded from the extrusion head.

[0011] Furthermore, the defoaming module includes an extrusion cylinder and defoaming rods. The extrusion cylinder is rotatably connected to the extrusion tube and is arranged inside the extrusion tube. The defoaming rods are fixedly connected to the screw rod. The central axis of the defoaming rods coincides with the central axis of the screw rod. The defoaming rods are arranged inside the extrusion cylinder and are fixedly connected to the extrusion cylinder.

[0012] When the raw materials are extruded into the extrusion cylinder, the defoaming rods continuously rotate driven by the screw rod, continuously stir the raw materials, break and eliminate the air bubbles in the raw materials, and improve the product quality.

[0013] Furthermore, the extrusion cylinder is divided into two sections. The two sections of the extrusion cylinder are connected end to end, and the outlet of the extrusion cylinder near the extrusion head is smaller than the outlet of the other section of the extrusion cylinder. Defoaming rods are arranged in both sections of the extrusion cylinder.

[0014] The outlet of the extrusion cylinder of the section away from the extrusion head is smaller than the inlet of the extrusion cylinder. After the raw materials are stirred by the defoaming rods in the extrusion cylinder of the section away from the extrusion head, they are subjected to a primary extrusion at the outlet of the extrusion cylinder of the section away from the extrusion head, and the raw materials are compacted once; the raw materials after the primary compaction enter the latter section of the extrusion cylinder, are stirred by the defoaming rods again, further eliminate the air bubbles. When passing through the outlet of the latter section of the extrusion cylinder, the raw materials are secondarily compacted, further improving the elimination rate of the air bubbles in the raw materials.

[0015] Furthermore, the cooling module includes a primary cooling unit and a secondary cooling unit. One end of the primary cooling unit is fixedly connected to the extrusion head and is in communication with the extrusion head. The other end of the primary cooling unit is fixedly connected to the secondary cooling unit. The secondary cooling unit is fixedly connected to the workbench.

[0016] The primary cooling unit pre-cools the extruded raw materials, preventing quality problems such as cracks, bending, and flow marks from occurring when the raw materials are shaped due to a sudden drop in temperature. The primary cooling unit and the secondary cooling unit cooperate to enable the raw materials to be cooled smoothly.

[0017] Further, the primary cooling unit includes a primary cooling pipe and a bimetallic strip. The primary cooling pipe is fixedly connected to the secondary cooling unit. A cooling pipeline, an adaptive pipeline, and an output pipeline are arranged inside the primary cooling pipe. The cooling pipeline and the adaptive pipeline surround the output pipeline. A cooling inlet, a cooling outlet, an adaptive inlet, and an adaptive outlet are arranged on the primary cooling pipe. One ends of all the cooling pipelines converge at the cooling inlet, and the other ends of all the cooling pipelines converge at the cooling outlet. One ends of all the adaptive pipelines converge at the adaptive inlet, and the other ends of all the adaptive pipelines converge at the adaptive outlet. One end of the bimetallic strip is arranged in the adaptive pipeline in an array, and the other end of the bimetallic strip is fixedly connected to the primary cooling pipe. A regulating bin is arranged above the outlet of each output pipeline, and part of the secondary cooling unit is arranged in the regulating bin.

[0018] Cooling water enters the cooling pipeline and the adaptive pipeline from the cooling inlet and the adaptive inlet respectively. The raw material extruded from the extrusion head is conveyed in the output pipeline. The cooling water in the cooling pipeline cools the raw material in the output pipeline. When the temperature of the raw material in the output pipeline is higher than the preset value, the bimetallic strip is heated and bends to one side, and the adaptive pipeline is continuously opened. The cooling water enters the adaptive pipeline to supplement and cool the raw material in the output pipeline, improving the cooling efficiency of the primary cooling unit.

[0019] Further, the secondary cooling unit includes a blowing pipe, a solenoid valve, a fixed shell, a conveying roller, and a regulating structure. The fixed shell is arranged on the workbench and fixedly connected to the workbench. The fixed shell is fixedly connected to the primary cooling pipe. The blowing pipe is inserted into the fixed shell and fixedly connected to the fixed shell. The blowing pipe is arranged on the extension line of the output pipeline. A solenoid valve is arranged at the inlet of the blowing pipe on the extension line of each output pipeline. The solenoid valve is signal-connected to the regulating structure. The conveying roller is arranged below the output pipeline and rotatably connected to the fixed shell. The regulating structure is arranged in the regulating bin and fixedly connected to the primary cooling pipe.

[0020] After the primary cooling unit has been used for a long time, the cooling pipeline and the adaptive pipeline inside it will become blocked, reducing the cooling effect. When the raw material is output from the primary cooling unit, the regulating structure will detect its temperature. When the detected temperature is higher than the preset value, the regulating structure sends a signal. The solenoid valve is provided with a signal receiver for receiving the signal, and the channel of the solenoid valve opens wider, allowing more air to enter the blowing pipe to cool the raw material conveyed on the conveying roller faster. When the detected temperature is lower than the preset value, the regulating structure sends a signal. The solenoid valve is provided with a signal receiver for receiving the signal, and the channel of the solenoid valve opens smaller, allowing less air to enter the blowing pipe to cool the raw material conveyed on the conveying roller more gently, while reducing noise.

[0021] Furthermore, the adjustment structure includes a shape resetting member, a power source, a circuit board, a brush, a resistor, and a sliding seat. The shape resetting member, the power source, the circuit board, the brush, the resistor, and the sliding seat are all located inside the adjustment chamber. The sliding seat is fixedly connected to the primary cooling pipe, the resistor is fixedly connected to the sliding seat, the brush is slidably connected to the sliding seat and is also slidably connected to the resistor. The power source is fixedly connected to the primary cooling pipe, the circuit board is fixedly connected to the primary cooling pipe and is signal-connected to the solenoid valve. One end of the shape resetting member is fixedly connected to the primary cooling pipe, and the other end is fixedly connected to the brush. The power source, the circuit board, the brush, and the resistor are connected in series.

[0022] The shape resetting member is made of shape memory alloy and will deform when heated. After deformation, it will drive the brush to slide on the sliding seat. After sliding, the resistance value in the circuit composed of the power source, the circuit board, the brush, and the resistor changes. When the temperature inside the adjustment chamber continuously rises, the shape resetting member drives the brush to slide, the resistance in the circuit decreases, the current increases, the circuit board detects the current change, the signal generator on the circuit board emits a signal, the signal receiver on the solenoid valve receives the signal, and the opening degree of the channel inside the solenoid valve becomes larger; when the temperature inside the adjustment chamber decreases, the shape resetting member drives the brush to slide, the resistance in the circuit increases, the current decreases, the circuit board detects the current change, the signal generator on the circuit board emits a signal, the signal receiver on the solenoid valve receives the signal, and the opening degree of the channel inside the solenoid valve becomes smaller, realizing the adaptive regulation of the secondary cooling unit.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The defoaming module of the present invention can eliminate the bubbles inside the raw materials in a molten state before extrusion molding, ensuring the quality of the product;

[0025] 2. By setting the primary cooling unit, the present invention realizes the additional cooling of the molding raw materials passing through the primary cooling unit adaptively, ensuring that the molding raw materials can be cooled to the preset temperature range after passing through the primary cooling unit;

[0026] 3. By setting the secondary cooling unit, the present invention realizes the rapid cooling of the molding raw materials. When the molding raw materials are output from the primary cooling unit, the adjustment structure will detect the temperature of the molding raw materials and then feedback it to the solenoid valve. The air flow in the blowing pipe is controlled by the solenoid valve. When the temperature of the molding raw materials is higher than the preset value, the opening degree of the solenoid valve becomes larger and the air volume becomes more, increasing the cooling rate of the molding raw materials; when the temperature of the molding raw materials is lower than the preset value, the opening degree of the channel of the solenoid valve becomes smaller and the air volume becomes smaller, preventing overcooling and affecting the product quality.

Specific embodiments

[0037] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment: As Figure 1 - Figure 9 shown, the present invention provides a technical solution for an extrusion molding device for rapidly cooling PP coil raw materials:

[0039] As Figure 1 and Figure 2As shown in the figure, the extrusion molding device includes a workbench 1, an extrusion tube 2, a driving module 3, a defoaming module 4, an extrusion head 5 and a cooling module 6. The extrusion tube 2 is arranged on the workbench 1 and fixedly connected to the workbench 1. The driving module 3 is inserted from one end of the extrusion tube 2 and fixedly connected to the extrusion tube 2. One end of the extrusion head 5 is fixedly connected to the other end of the extrusion tube 2, and the other end is fixedly connected to the cooling module 6. The extrusion head 5 is arranged on the workbench 1 and fixedly connected to the workbench 1. The defoaming module 4 is arranged at one end of the extrusion tube 2 close to the extrusion head 5 and is rotatably connected to the extrusion tube 2. The defoaming module 4 is fixedly connected to the driving module 3. The cooling module 6 is arranged on the workbench 1 and fixedly connected to the workbench 1.

[0040] The workbench 1 serves as the installation foundation of the extrusion molding device to keep the extrusion molding device stable. The molten raw material enters the extrusion tube 2 from the inlet of the extrusion tube 2. The driving module 3 conveys the raw material from the inlet of the extrusion tube 2 to the defoaming module 4. When the driving module 3 works, it drives the defoaming module 4 to rotate at the same time. When the raw material passes through the defoaming module 4, the internal bubbles are eliminated, and then it is extruded through the extrusion head 5. The extruded strip-shaped raw material enters the cooling module 6 for rapid cooling, improving the production efficiency.

[0041] As Figure 1 and Figure 2 shown in the figure, a feed hopper 21 is arranged at the inlet of the extrusion tube 2, and the feed hopper 21 is fixedly connected to the extrusion tube 2.

[0042] Setting the feed hopper 21 facilitates the continuous entry of a large amount of raw material into the extrusion tube 2.

[0043] As Figure 2 shown in the figure, the driving module 3 includes a driving motor 31, a screw 32 and a mounting shell 33. The driving motor 31 is fixedly connected to the workbench 1. The output rod of the driving motor 31 is fixedly connected to the screw 32. The screw 32 passes through the mounting shell 33, is inserted into the extrusion tube 2, and is rotatably connected to the mounting shell 33. The screw 32 is fixedly connected to the defoaming module 4. The mounting shell 33 is fixedly connected to the extrusion tube 2 and is arranged at one end of the extrusion tube 2.

[0044] The mounting shell 33 assists in the fixed positioning of the screw 32. The driving motor 31 drives the screw 32 to rotate, transmitting the raw material in the extrusion tube 2. Under the continuous transmission and extrusion of the screw 32, the raw material is extruded from the extrusion head 5.

[0045] As Figure 5 shown in the figure, the defoaming module 4 includes an extrusion cylinder 41 and a defoaming rod 42. The extrusion cylinder 41 is rotatably connected to the extrusion tube 2 and is arranged inside the extrusion tube 2. The defoaming rod 42 is fixedly connected to the screw 32. The central axis of the defoaming rod 42 coincides with the central axis of the screw 32. The defoaming rod 42 is arranged inside the extrusion cylinder 41 and is fixedly connected to the extrusion cylinder 41.

[0046] When the raw material is squeezed into the extrusion cylinder 41, the defoaming rod 42 is driven by the screw 32 to continuously rotate, continuously stir the raw material, break and eliminate the bubbles in the raw material, and improve the product quality.

[0047] like Figure 5 As shown, the extrusion cylinder 41 is divided into two sections, the two sections of the extrusion cylinder 41 are connected end to end, and the outlet of the section of the extrusion cylinder 41 close to the extrusion head 5 is smaller than the outlet of the other section of the extrusion cylinder 41 , and debubbling rods 42 are provided in both sections of the extrusion cylinder 41 .

[0048] The outlet of the extrusion cylinder 41 of the section away from the extrusion head 5 is smaller than the inlet of the extrusion cylinder 41. After the raw material is stirred by the debubble rod 42 in the extrusion cylinder 41 of the section away from the extrusion head 5, it is extruded once at the outlet of the extrusion cylinder 41 of the section away from the extrusion head 5 to compact the raw material once; the raw material after the first compaction enters the latter section of the extrusion cylinder 41 and is stirred again by the debubble rod 42 to further eliminate bubbles. When passing through the outlet of the latter section of the extrusion cylinder 41, the raw material is compacted for the second time, further improving the elimination rate of bubbles in the raw material.

[0049] like Figure 1 and Figure 2 As shown, the cooling module 6 includes a primary cooling unit 61 and a secondary cooling unit 62. One end of the primary cooling unit 61 is fixedly connected to the extrusion head 5 and communicates with the extrusion head 5. The other end of the primary cooling unit 61 is fixedly connected to the secondary cooling unit 62. The secondary cooling unit 62 is fixedly connected to the workbench 1.

[0050] The primary cooling unit 61 pre-cools the raw material after extrusion to prevent quality problems such as cracks, bends, flow marks, etc. from occurring when the raw material is shaped due to a sudden drop in temperature. The primary cooling unit 61 and the secondary cooling unit 62 cooperate to ensure a smooth cooling of the raw material.

[0051] like Figure 3 , Figure 6 , Figure 7 and Figure 8As shown in the figure, the primary cooling unit 61 includes a primary cooling pipe 611 and a bimetallic strip 612. The primary cooling pipe 611 is fixedly connected to the secondary cooling unit 62. A cooling pipeline 613, an adaptive pipeline 614, and an output pipeline 615 are arranged inside the primary cooling pipe 611. The cooling pipeline 613 and the adaptive pipeline 614 surround the output pipeline 615. A cooling inlet 6111, a cooling outlet 6112, an adaptive inlet 6113, and an adaptive outlet 6114 are arranged on the primary cooling pipe 611. One ends of all the cooling pipelines 613 converge at the cooling inlet 6111, and the other ends of all the cooling pipelines 613 converge at the cooling outlet 6112. One ends of all the adaptive pipelines 614 converge at the adaptive inlet 6113, and the other ends of all the adaptive pipelines 614 converge at the adaptive outlet 6114. One end of the bimetallic strip 612 is arranged in the adaptive pipeline 614 in an array, and the other end of the bimetallic strip 612 is fixedly connected to the primary cooling pipe 611. An adjustment bin is arranged above the outlet of each output pipeline 615, and part of the secondary cooling unit 62 is arranged in the adjustment bin.

[0052] Cooling water enters the cooling pipeline 613 and the adaptive pipeline 614 from the cooling inlet 6111 and the adaptive inlet 6113 respectively. The raw material extruded from the extrusion head 5 is conveyed in the output pipeline 615. The cooling water in the cooling pipeline 613 cools the raw material in the output pipeline 615. When the temperature of the raw material in the output pipeline 615 is higher than the preset value, the bimetallic strip 612 is heated and bends to one side, and the adaptive pipeline 614 is continuously opened. The cooling water enters the adaptive pipeline 614 to supplement and cool the raw material in the output pipeline 615, improving the cooling efficiency of the primary cooling unit 61.

[0053] As Figure 3 and Figure 9 shown in the figure, the secondary cooling unit 62 includes a blowing pipe 621, a solenoid valve 622, a fixed shell 623, a conveying roller 624, and an adjustment structure 625. The fixed shell 623 is arranged on the workbench 1 and fixedly connected to the workbench 1. The fixed shell 623 is fixedly connected to the primary cooling pipe 611. The blowing pipe 621 is inserted into the fixed shell 623 and fixedly connected to the fixed shell 623. The blowing pipe 621 is arranged on the extension line of the output pipeline 615. A solenoid valve 622 is arranged at the inlet of the blowing pipe 621 on the extension line of each output pipeline 615. The solenoid valve 622 is signal-connected to the adjustment structure 625. The conveying roller 624 is arranged below the output pipeline 615. The conveying roller 624 is rotatably connected to the fixed shell 623. The adjustment structure 625 is arranged in the adjustment bin and fixedly connected to the primary cooling pipe 611.

[0054] After the primary cooling unit 61 has been used for a long time, the cooling pipeline 613 and the adaptive pipeline 614 inside it will become blocked, reducing the cooling effect. When the raw material is output from the primary cooling unit 61, the temperature detection structure 625 will detect its temperature. When the detected temperature is higher than the preset value, the temperature detection structure 625 sends a signal. The solenoid valve 622 is provided with a signal receiver for receiving the signal, and the channel of the solenoid valve 622 opens wider, allowing more air volume to enter the air blowing pipe 621, and cooling the raw material conveyed on the conveying roller 624 faster. When the detected temperature is lower than the preset value, the temperature detection structure 625 sends a signal. The solenoid valve 622 is provided with a signal receiver for receiving the signal, and the channel of the solenoid valve 622 opens smaller, allowing less air volume to enter the air blowing pipe 621, cooling the raw material conveyed on the conveying roller 624 more gently, and reducing noise at the same time.

[0055] As Figure 5 shown, the temperature detection structure 625 includes a shape reset member 6251, a power source 6252, a circuit board 6253, a brush 6254, a resistor 6255, and a sliding seat 6256. The shape reset member 6251, the power source 6252, the circuit board 6253, the brush 6254, the resistor 6255, and the sliding seat 6256 are all located in the adjustment chamber. The sliding seat 6256 is fixedly connected to the primary cooling pipe 611, the resistor 6255 is fixedly connected to the sliding seat 6256, the brush 6254 is slidably connected to the sliding seat 6256 and is also slidably connected to the resistor 6255. The power source 6252 is fixedly connected to the primary cooling pipe 611, the circuit board 6253 is fixedly connected to the primary cooling pipe 611 and is signal-connected to the solenoid valve 622. One end of the shape reset member 6251 is fixedly connected to the primary cooling pipe 611, and the other end is fixedly connected to the brush 6254. The power source 6252, the circuit board 6253, the brush 6254, and the resistor 6255 are connected in series.

[0056] The shape resetting member 6251 is made of a shape memory alloy and will deform when heated. After deformation, it will drive the brush 6254 to slide on the slide base 6256. After sliding, the resistance value in the circuit composed of the power supply 6252, the circuit board 6253, the brush 6254 and the resistor 6255 changes. When the temperature in the adjustment chamber continuously rises, the shape resetting member 6251 drives the brush 6254 to slide, the resistance in the circuit decreases, the current increases, the circuit board 6253 detects the current change, the signal generator on the circuit board 6253 emits a signal, the signal receiver on the solenoid valve 622 receives the signal, and the opening degree of the channel in the solenoid valve 622 becomes larger; when the temperature in the adjustment chamber decreases, the shape resetting member 6251 drives the brush 6254 to slide, the resistance in the circuit increases, the current decreases, the circuit board 6253 detects the current change, the signal generator on the circuit board 6253 emits a signal, the signal receiver on the solenoid valve 622 receives the signal, and the opening degree of the channel in the solenoid valve 622 becomes smaller, realizing the adaptive regulation of the secondary cooling unit 62.

[0057] The working principle of the present invention: The workbench 1 serves as the installation foundation of the extrusion molding equipment to maintain the stability of the extrusion molding equipment. The molten raw material enters the extrusion tube 2 from the inlet of the extrusion tube 2. The driving module 3 conveys the raw material from the inlet of the extrusion tube 2 to the defoaming module 4. When the driving module 3 works, it drives the defoaming module 4 to rotate at the same time. When the raw material passes through the defoaming module 4, the internal bubbles are eliminated, and then it is extruded through the extrusion head 5. The extruded strip-shaped raw material enters the cooling module 6 to rapidly cool down, improving the production efficiency.

[0058] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
